Notes about the control relays:
• The control relay +0: Reading all parameters
When this bit is turned off to on, all parameters stored in the ROM of the PID module are read out and stored in the data
registers in the CPU module.
• The control relay +1: Loading initial values
When the user program is downloaded to the CPU module, the initial values of all parameters for the PID module are
also downloaded and stored in the ROM of the CPU module. When this bit is turned off to on, the initial values stored in
the ROM are loaded into the data registers (RAM).
• The control relay +2: Writing all parameters
When this bit is turned off to on, all parameters stored in the data registers are written to the ROM of the PID module.
• The control relay +3 through +27: Writing blocks 2 to 5, 10 to 19, and 30 to 39
When the writing bit is turned off to on, the corresponding block parameters stored in the data registers are written to the
ROM of the PID module.
Data Flow of the PID module parameters
ROM
1. All parameters are read out from the PID module and stored in the data registers in the CPU module
when the reading all parameters bit is turned off to on.
2. Initial values stored in the ROM of the CPU module are loaded to the data registers when the loading
initial values bit is turned off to on.
3. All parameters stored in the data registers are written to the PID module when the writing all parameters
bit is turned off to on.
4. The block parameters stored in the data registers are written to the PID module when the block writing bit
is turned off to on.
Note:
The communication status between the CPU module and the PID module can be confirmed with the following data register.
• When both CH0 and CH1 are in fixed value control mode: First data register + 189
• When CH0 or CH1 is in program control mode: First data register + 589

Turn off the MicroSmart and connect the PID module again.
The PID module is not connected to the configured slot number. Turn off
the MicroSmart and connect the PID module to the appropriate slot
number.
