YASKAWA VIPA SPEED7 - FB 71 - TCP_MB_SERVER - Modbus;Tcp Server

5. Set M101.0 in the CPU to TRUE.
ð
The Modbus request is sent and it is waited for a response.
If M101.0 is automatically reset, the job was finished without errors and the read
data are stored in the CPU starting from bit memory byte 200. MW108 returns
7004h and indicates waiting for a new job.
If M101.0 is not automatically reset and MW108 returns non-zero, an error has
occurred. The cause of error can be read by the code of MW108 (e.g. MW108 =
8382h when the start address 2000 in the server is not available). MW108
returns 7004h and indicates waiting for a new job.
