Hi.
Anyone here ever handled word IO between PLC Mitsubishi and DSQC 378B via Buffer memory of CC-Link module (QJ61BT11N)?
I read some PLC program with following configuration:
- Master module: QJ61BT11N, start XY=0020
- Intelligent device: D378B, StatNo=1, OccStat=4, BasicIO=1.
Assume that PLC wants to read 16 points word from Robot then save to PLC registers, Robot words mapping from 112
Below is a image that I cut from Mitsubishi manual, buffer memory address of station 1 starts from H2E0 -> H2E3. But in PLC program, I always see they read from H2E1.
(PLC instruction: FROM H2 H2E1 D5000 K16)
Please tell me the reason if you know. Thank you.
