4.5 Timing for Transm ission of Communication Setting
Data
1. The MCU communciation setting data by the tool is stored in the CPU
during the program
download.
2. The MCU communication setting data which is stored in the CPU unit is automatically set in the MCU
when the power turns on, or
when changing the mode PROG >RUN.
3.
When a communication parameter is specified during the exeuction of F159 (MTRN) instruciton, it
is set in the MCU.
Key Point:
When setting the communication parameter in the MCU, the communciation channel will be reset.
(It takes about 1 second to complete the COM. port setting.)
However, this operation is not applied in case of the PC(PLC) link mode. In the PC(PLC) link
communication, only unit No. can be changed, and if the parameter is changed by F159 (MTRN)
instruction, the communciation will not be reset.
Reset means “Abort sending” and “Clear receiving and error”. (However, some errors cannot be
cleared.)
Therefore, when the MCU setting is carried out by the tool, the data which is received in the PROG.
mode will be all cleared when the mode is switched to the RUN mode.
