CONFIGURING PID MODULE USING WINDLDR
6-4 FC5A MicroSmart PID Module User’s Manual FC9Y-B1283
User Program Download
The user program contains the user program and the PID module parameters (initial values) configured
in the PID Module Configuration dialog box. After the user program is downloaded to the CPU module,
the CPU module can communicate with the PID Modules through the allocated data registers.
After the user program download, the following actions will be taken depending on whether Write PID
Module parameters after download in the Download dialog box is checked or not.
When Write PID Module parameters after download is checked:
After the user program is downloaded to the CPU module, the PID module parameters configured in the
PID Module Configuration dialog box are written to the CPU module and the connected PID modules.
When Write PID Module parameters after download is not checked:
After the user program is downloaded to the CPU module, the PID module parameters are not written to
the PID module.
When Write PID Module parameters after download is checked, after the user program is downloaded
to the CPU module, the PID module parameters configured in the PID Module Configuration dialog box
will be written to the data registers in the CPU module and all PID modules configured in the Expansion
Modules Configuration dialog box. However, if a PID module is not connected to the configured slot,
writing parameters to the PID module will fail. Even after writing parameters to one PID module failed,
WindLDR continues to write the parameters to all PID modules configured in the Expansion Modules
Configuration dialog box.
If writing parameters fails, connect the PID module to the CPU module and write parameters to the PID
module again.
To write the PID module parameters without downloading the user program to the CPU module, take the
following steps:
1. Connect the PID module to the CPU module.
2. Open the PID Module Configuration dialog box for the slot.
3. Click on Write All Parameters button.
All the configured parameters will be written to the data registers in the CPU module and the PID
module.
