Appendix 1.2
(1) Initial data setting request flag (RY9)
Write parameter data to the remote buffer memory area and turn on this signal to set or change the operating
condition of the temperature control module with the program.
Initial data setting completed flag (RX9) turns on when the operating condition is changed.
For the parameters which the temperature control module can change with this signal, refer to the following.
• Lists of Remote Buffer Memory Areas (Page 49, Section 3.7)
The temperature control module accepts the signal only when all channels are stopped. Therefore, stop operations of all
channels and turn on the signal.
If the signal is turned on while even one channel is operating, an error occurs (error code: 0003H) and the signal is not
accepted.
(2) Error clear request flag (RYA)
If this signal is turned on and off when the following errors have occurred, Error flag (RXA) turns off.
• Error code: 0003H, and Error occurrence address: FFFFH
• Error code: 0006H
(a) To clear an error history
An error history is not cleared by turning on this signal. To clear an error history, use Error history clear
command (address: 1000H). For Error history clear command (address: 1000H), refer to the following.
• Error history clear command (address: 1000H) (Page 364, Appendix 3 (70))
(3) During operation setting change instruction (RY10)
Turn on this signal to change parameters during operation of the temperature control module. If the setting
changes are normally completed, During operation setting change completion flag (RX10) turns on.
Changed values of parameters are enabled for channels where the operations are stopped.
The following table lists signals to be used for the parameter changes. ( indicates that the parameter changes
are enabled, and indicates that the parameter changes are disabled.)
All channels are stopped.
