Introduction

1.2.2 Power Up Initialization

The Moore 353 will retain, in the station NVRAM, calculated block values (e.g. outputs, elapsed time, last
input/output logic states), including the time since power was lost. Three power up modes (hot, warm, and cold) are
utilized in the Moore 353 that affect the initialization of function blocks. These modes are configured by two power
up timers (warm and cold), included in STATION parameters. The station will initialize a hot start when power up
occurs prior to the expiration of the warm timer. A cold start will occur when power up occurs after the expiration
of the cold timer and a warm start will take place when the station powers up after the expiration of the warm timer
but prior to the expiration of the cold timer.
1
Hot Start
- All function block execution continues from the last state prior to power fail.
1
Warm Start
- Function blocks that have a power up in a last state feature, either by design or by configuration
selection, will power up as defined in the individual block descriptions. All other function blocks will initialize at
cold start conditions.
1
Cold Start
- All function block outputs will initialize at 0 unless otherwise stated in individual block descriptions.

1.2.3 Configuration

The Moore 353 can be configured either locally or remotely. First, the local faceplate includes buttons located
behind a flip-down door for complete configuration including the addition/deletion of loops and function blocks and
the editing of function block parameters. Section 2 Configuration Overview includes a road map for stepping
through configuration. Certain block parameters (e.g. gains, constants) can be edited while on-line but design
changes (e.g. block interconnections, block additions) will put the station in "configuration hold" which will hold
outputs at the current value until the Exit button is pressed. This will enable bumpless changes to be made while
on-line.
The second method is to use the Graphical Configuration program. A
configuration can be downloaded to a controller either via the port on the local
faceplate or over a network (either Modbus, Ethernet, or LIL). During a
download, all outputs will be held and the controller will retain all the
intermediate calculations of all the blocks it had been running prior to the
download. After the download, all function block parameters with the same tag
name as those held will be used to initialize the downloaded function block
parameters, thus providing a bumpless download under these conditions. If a
loop tag name is changed, the tag names of all function blocks within that loop
will change and will, therefore, require re-initialization of all of these blocks.
However, the loop tag can be changed from the local faceplate without causing
re-initialization, providing a bumpless tag change.

1.3 PRODUCT SUPPORT

Product support can be obtained from a customer service center (i.e. Technical Support Group in North America or
a Technical Information Center (TIC) in Asia or Europe). Each region has a customer service center that provides
direct telephone support on technical issues related to the functionality, application, and integration of the product.
Regional contact information is provided below. Your regional Technical Support Group or TIC is the first place to
call when seeking product support information. When calling, it is helpful to have the following information ready:
Product part number or model number and version
If there is a problem with product operation:
- Whether or not the problem is intermittent
- The steps performed before the problem occurred
- Any status message, error messages, or LED indications displayed
- Installation environment
