Input/output (with another analog module) function
Input and output can be processed using other analog modules (such as an A/D converter module or D/A converter
module) in the system.
(1) Input
In general, a temperature control module uses the temperature measured through thermocouples or platinum
resistance thermometers connected to the module as a temperature process value (PV). In the temperature
control module, the digital input value of current or voltage converted by other analog modules (such as an A/D
converter module) in the system can also be used as a temperature process value (PV).
(a) Setting method
1.
Set "Method selection" to "Param write" of the control mode to be used.
"CC IE Field Configuration" windowSelect the temperature control module from "List of
stations"[CC IE Field Configuration][Online][Parameter Processing of Slave Station]
2.
Select any one of setting values from "201: Other analog module input (0-4000): 0 to 4000 (1 unit)"
to "205: Other analog module input (0-32000): 0 to 32000 (1 unit)" for "CH Input range".
3.
Store the value of another analog module (such as an A/D converter module) into CH
Temperature process value for input with another analog module (PV) (RWw0 to RWw3).
● If the second procedure above is executed ahead of the first procedure, a write data error (error code: 0004H) occurs.
● When this function is used, the value in the following remote register is used for the temperature process value (PV)
scaling function.
• CH Temperature process value for input with another analog module (PV) (RWw0 to RWw3)
For details on the temperature process value (PV) scaling function, refer to the following.
