Page 24 System Description S5-90U/S5-95U S5-95U Programmable Controller The S5-95U is a fast and compact PLC designed for complex applications with digital and analog inputs and outputs where space is a crucial factor. It is suitable for small control tasks with high demands regarding response times and supplementary functions.
Page 25: System Description
S5-90U/S5-95U System Description Dimensions The S5-90U and S5-95U programmable controllers are distinguished by their low space requirement. They can be used even in places too small for accommodating a conventional control consisting of contactors and relays. They are thus the ideal solution if a controller for a small control task must additionally be fitted in a control cabinet already containing a complete configuration.
Page 26: All Inputs And Outputs
System Description S5-90U/S5-95U Digital Inputs/Outputs Due to their wide range of applications, the number of inputs and outputs required by the PLCs varies considerably. The two PLCs permit different configurations. You can therefore select the PLC that suits your specific task. Table 1-2.
Page 27: Retentive And Non-Retentive Operands
S5-90U/S5-95U System Description Your PLC needs a program to carry out its control task. Depending on the task involved, these programs can vary and place various demands on the PLCs. User Memory The program is loaded into the user memory when the PLC is started up. The memory capacity represents a limiting factor for the size of the program so that, for instance, extensive programs cannot be executed in every PLC.
Page 28: Software Overview
System Description S5-90U/S5-95U PID Controller Many applications require PID control functions in addition to the usual control tasks. For this purpose, the operating system of the S5-95U has a PID controller which can be called up from the program. The PID controller forms an integral part of the PLC's operating system and therefore takes up no space in the user memory.
Page 29: Communications Capabilities
PROFIBUS standard (DIN 19245). The open LAN architecture permits the connection of non-Siemens field devices. However, it is also possible to link S5-95U PLCs only.
Page 30 System Description S5-90U/S5-95U Conventional controls using relays or contactors are hardwired. Their functions are implemented by wiring the switching elements. If the control task changes, time-consuming modifications of the wiring have to be made. In a programmable controller, however, rewiring is taken over by the program. Modifications of functions, testing and start-up are thus considerably facilitated.
Page 31 S5-90U/S5-95U System Description STEP 5 Versions STEP 5 is available in two different versions to come up to the various demands placed on the soft- ware: • STEP 5 for mini PLCs is designed especially for programming the S5-90U, S5-95U and S5-100U programmable controllers.

Page 42 Technical Description S5-90U/S5-95U The operating system is stored in a ROM. It is thus fixed and cannot be changed. All dynamic variables are stored in the RAM. These are the following: • STEP 5 program and compiled program. The STEP 5 program cannot be processed unless it is transformed by a compiler into a form that can be interpreted by the processor and arithmetic unit.
Page 43 S5-90U/S5-95U Technical Description Note An interference pulse lasting approximately 150 µs is generated on switching on the supply voltage to the onboard I/O. "Normal" inputs do not accept this pulse. High-speed inputs (e. g. counters) recognize this pulse as a singal. Programmer Interface Interface for a programmer or operator control and monitoring device (TD or OP).
Page 44: Peculiarities Of The Plcs
Technical Description S5-90U/S5-95U 2.3.2 Peculiarities of the PLCs The STEP 5 program developed by the user is not directly executed by the processor and arithmetic unit. It must first be translated by a compiler so that it can be interpreted by the processor and arithmetic unit.
Page 45 S5-90U/S5-95U Technical Description Only the compiled program is executed by the processor and arithmetic unit whereas the STEP 5 program remains in the RAM. It can be read back into the programmer. In comparison with other PLCs whose processors and arithmetic units are able to process the STEP 5 program, this procedure involves some peculiarities when using the S5-90U/95U PLCs.

Swing the interface module back until the slide on the bottom snaps into place on the rail. Use the flat ribbon cable to connect the module to the last bus unit. Use connecting cable 712-8 to join the two interface modules (in the case of the IM 318).
Page 61: Cabinet Mounting
S5-90U/S5-95U Installation Guidelines 3.2.5 Cabinet Mounting To help prevent noise, mount the programmable controller on a metal plate. The connections between the mounting rails should have a low impedance. Make sure that the system is bonded to earth. You can use the 8LW system or the 8LX system mounting plates (see Catalog NV 21). A minimum clearance of 210 mm between two mounting rails should be adhered to.
Page 62 Installation Guidelines S5-90U/S5-95U Vertical Mounting You can also mount the standard mounting rails vertically and then attach the modules one over the other. Because heat dissipation by convection is less effective in this case, the maximum ambient temperature allowed is 40° C (104° F). Use the same minimum clearances for a vertical configuration as for a horizontal configuration.

Page 79 S5-90U/S5-95U Installation Guidelines Note It is imperative that you connect the reference potential of the load power supply unit with the L- terminal of the module in the case of 24 V DC digital output modules. If this connection is missing (e.g. wirebreak), a current of typically 15 mA can flow at the outputs.
Page 80 Installation Guidelines S5-90U/S5-95U Warning If you use non-floating I/O modules, you must provide an external connection between the chassis ground of the non-floating I/O module and the chassis ground of the CPU. Example of a Floating Configuration with Digital Modules A floating configuration is required in the following situations.
Page 81: Wiring Arrangement, Shielding And Measures Against Electromagnetic Interference
S5-90U/S5-95U Installation Guidelines Wiring Arrangement, Shielding and Measures against Electromagnetic Interference This section describes the wiring arrangements for bus cables, signal cables, and power supply cables that guarantee the electromagnetic compatibility (EMC) of your installation. 3.5.1 Running Cables Inside and Outside a Cabinet Dividing the lines into the following groups and running the groups separately will help you to achieve electromagnetic compatibility (EMC).
Page 82: Running Cables Outside Buildings
Install these protective elements at the point where the cable enters the building. Note Lightning protection measures always require an individual assessment of the entire system. If you have any questions, please consult your local Siemens office or any company specializing in lightning protection. Grounding Make certain that you have sufficient equipotential bonding between the devices.
Page 83: Equipotential Bonding
S5-90U/S5-95U Installation Guidelines 3.5.3 Equipotential Bonding Potential differences may occur between separate sections of the system if • Programmable controllers and I/Os are connected via non-floating interface modules or • Cables are shielded at both ends but grounded via different sections of the system. Potential differences may be caused, for instance, by differences in the system input voltage.
Page 84: Shielding Cables
Installation Guidelines S5-90U/S5-95U 3.5.4 Shielding Cables Shielding is a measure to weaken (attenuate) magnetic, electric or electromagnetic interference fields. Interference currents on cable shields are discharged to ground over the shield bar which has a conductive connection to the housing. So that these interference currents do not become a source of noise in themselves, a low-resistance connection to the protective conductor is of special importance.
Page 85: Special Measures For Interference-Free Operations
S5-90U/S5-95U Installation Guidelines Note the following when connecting the cable shield: • Use metal cable clamps for fixing the braided shield. The clamps have to enclose the shield over a large area and make good contact (see Figure 3-32). • Connect the shield to a shield bar immediately at the point where the cable enters the cabinet.
Page 86 Installation Guidelines S5-90U/S5-95U Mains Connection for Programmers Provide a power connection for a programmer in each cabinet. The plug must be supplied from the distribution line to which the protective ground for the cabinet is connected. Cabinet Lighting Use, for example, LINESTRA® lamps for cabinet lighting. Avoid the use of fluorescent lamps since these generate interference fields.

S5-90U/S5-95U Addressing and Access to I/Os Addressing and Access to I/Os The S5-90U and the S5-95U have two types of inputs and outputs. The inputs and outputs located on the programmable controller itself are called onboard I/Os. The S5-100U modules that expand your programmable controller are called external I/Os.

Page 284: Interrupt Priority
Onboard Interrupt Inputs S5-90U/S5-95U 10.3 Interrupt Priority In the S5-90U: You cannot stop interrupt processing once it has started. If an interrupt and a counter overflow occur simultaneously, interrupt processing has priority. Only one new cause for an interrupt can be stored while interrupt processing is running. If more causes for interrupts are present than can be stored, then they are ignored.
Page 285 S5-90U/S5-95U Onboard Interrupt Inputs Example of Interrupt Priorities: The cyclic program (OB1) is being processed in the S5-95U. An interrupt (signal edges) occurs at each of the inputs I 34.0 to 34.3. The sequence of the interrupts is shown in Figure 10-1. Inter- OB3 running and IB 35 specifies edge at I 34.0...
Page 286 Onboard Interrupt Inputs S5-90U/S5-95U More than eight Causes of Interrupts are Signalled to the S5-95U: If more causes of interrupts are present than can be stored in the "queue" (> eight interrupts), the corresponding number of additional entries is made in the diagnostic byte for the eighth interrupt (specification of several channels triggering interrupts).
Page 287: Calculating Interrupt Reaction Times
S5-90U/S5-95U Onboard Interrupt Inputs 10.4 Calculating Interrupt Reaction Times The interrupt reaction times is the amount of time that passes from the first occurence of an interrupt until the first statement in OB3 is called up. The interrupt reaction time is dependent upon the delay time of the interrupt input and upon the corresponding operating system run time.

Function Modules S5-90U/S5-95U Performance during Overflow If the enabled counter exceeds the counter range limit 65,535 the following actions occur. • Bit 3 (overflow) in the diagnostic byte is set to ”1” and • The outputs and diagnostic bits for ”setpoint reached” are disabled, but they remain unchanged The counting function continues.
