You need to set P160 - P179 to 0 or Modbus register No. of WJ200 / WL200. If you don't use
P162 - P169 and P172 - P179, you need to set these to 0.
When you set P160 to 0, setpoint data is STW1.
When you set P161 to 0, setpoint data is NSOLL_A.
When you set P170 to 0, setpoint data is ZSW1.
When you set P171 to 0, setpoint data is NIST_A.
When you want to set 32bit length data to P160 - P179, you need to set consecutively. If you don't
set consecutively, PNU 954 bit 4 becomes ON.
The byte order of 32bit length data depends on the setting of P160 - P179. For example, the
Modbus register No. 0x1001 is the high byte and 0x1002 is the low byte. When you want to set d001
to P171 and P172, you need to set either the followings.
- P171 = 0x1001, P172 = 0x1002
In this case, the high byte is sent first.
- P171 = 0x1002, P172 = 0x1001
In this case, the low byte is sent first.
