Appendix 7 Using The Module In The Redundant System With Redundant Extension Base Unit; Restricted Functions And Specifications - Mitsubishi Electric MELSEC iQ-R Series User Manual

Appendix 7
This chapter describes when the temperature control module is mounted on an extension base unit in a redundant system
with redundant extension base unit.

Unit
Restriction
If the system is switched during transition from setting mode to operation mode, starting ST may not start.
To start the starting ST properly, set "PID continuation flag" to "1: Continue."
If the system is switched during execution of the simultaneous temperature rise AT(auto tuning), the auto tuning may
stop.
To start the simultaneous temperature rise AT properly, set "PID continuation flag" to "1: Continue."
This function cannot be used.
When this function is used, a peak current suppression function master not exist error between multiple module (error
code: 1AE1H) occurs.
This function cannot be used.
When this function is used, a simultaneous temperature rise function master not exist error between multiple module
(error code: 1AF1H) occurs.
The interrupt program cannot be executed.
Restriction
If the system is switched during the mode shift processing, temperature control may become unstable.
To stabilize the temperature control, set "PID continuation flag" to "1: Continue."
When the system is switched, it may take time to stop the PID control.
Configure an external circuit to stop the PID control as necessary.
Restriction
Cannot be used.
When the FB is used, proper operation cannot be guaranteed.
