Appendix 2
This section describes details of remote register areas assigned to the master/local module.
The assignment of each device number is for the case when the remote register areas of the main module are
assigned to RWr0 to RWr1F and RWw0 to RWw1F.
For remote register areas indicated with the icons
unless otherwise specified.
• Proportional band (P): includes heating proportional band (Ph) and cooling proportional band (Pc).
• Manipulated value (MV): includes manipulated value for heating (MVh) and manipulated value for cooling (MVc).
• Transistor output: includes heating transistor output and cooling transistor output.
• Control output cycle: includes heating control output cycle and cooling control output cycle.
(1) Latest error code (RWr0)
An error code is stored when a moderate error or major error has occurred.
Turning on Error clear request flag (RYA) after eliminating the cause of the error clears the error code.
Errors that occurred in the past can be checked with Error history (address: A00H to FFFH). For the error
history, refer to the following.
• Error history (address: A00H to FFFH) (Page 363, Appendix 3 (69))
(2) Error occurrence address (RWr1)
The address of remote buffer memory area where an error has occurred is stored.
The contents of Error occurrence address (RWr1) differs depending on the error type. For details, refer to the
following.
• Lists of Error Codes (Page 271, Section 11.2)
(3) Latest warning code (RWr2)
An error code is stored when a minor error has occurred or an alarm code is stored when an alarm has occurred.
If a minor error has occurred, the error code is automatically cleared five seconds after the cause of the error is
eliminated.
If an alarm has occurred, the alarm code is automatically cleared after the cause of the alarm is eliminated.
Errors or alarms that occurred in the past can be checked with Error history (address: A00H to FFFH). For the
error history, refer to the following.
• Error history (address: A00H to FFFH) (Page 363, Appendix 3 (69))
