CH1 Temperature process value (PV) for input with another analog module
The digital input value of the current or voltage converted in another analog module (such as A/D converter module) on the
system can be used as a temperature process value (PV). Store the digital input value of the current or voltage converted by
another analog module (such as A/D converter module) in this area. For details, refer to the following:
Page 71 Input
When a value out of the set input range is stored, the value to be used for control is fixed to the upper limit
value or the lower limit value of the input range.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory area name
CH Temperature process value (PV) for input with another analog module
CH Temperature process value (PV) for input with another analog module (in
the Q compatible mode)
■Default value
The default value is 0.
CH1 Cooling proportional band (Pc) setting
Set the cooling proportional band (Pc) to execute the PID control. For details on this area, refer to the following:

CH Cooling proportional band (Pc) setting
CH Cooling proportional band (Pc) setting (in the Q compatible mode)
■Setting range
• In the R mode
1 to the full scale of the input range (())
• In the Q compatible mode
1 to 10000 (0.1% to 1000.0%)
■Default value
• In the R mode
For the R60TCTRT2TT2 and the R60TCTRT2TT2BW, the default value is 30 (30).
For the R60TCRT4 and the R60TCRT4BW, the default value is 30 (3.0).
• In the Q compatible mode
The default value is 30 (3.0%).
CH1 Memory's PID constants read command
PID constants are read from the non-volatile memory and stored in the buffer memory by using this command. Setting this
buffer memory area to Requested (1) stores the value backed up in the non-volatile memory to the buffer memory.
