2.4 Communications with MP-series Controllers
Message Functions
2-86
Register Type (PARAM16)
Gives the register type that was requested by the remote station.
This parameter is valid when using function code 43 hex only. The target register type is defined for
each function code from 01 to 10 hex.
Data Size (PARAM17)
This parameter gives the data size as the number of bits or words for read/write requests from the remote
station.
Remote CPU Module Number (PARAM18)
This parameter gives 1 if the remote device is an MP2000-series device.
This parameter indicates the remote CPU Module number if the remote device is a Yaskawa Controller
that is not a part of the MP2000 Series and it is comprised of multiple CPU Modules.
A 0 will be given for all other devices.
Reserved for System (PARAM19)
This parameter is used by the system.
Coil Offset (PARAM20 and PARAM21)
These parameters set the offset for the data address in the MP3000.
The MP3000 will offset the address back by the number of words specified by the offset. The data address
cannot be offset in the forward direction.
The Coil Offset parameter is used when the function code is 01, 05, 0F, 4341, 4345, or 434F hex. The
address is offset by the long-word offset in PARAM20 and PARAM21.
Input Relay Offset (PARAM22 and PARAM23)
These parameters set the offset for the data address in the MP3000.
The MP3000 will offset the address back by the number of words specified by the offset. The data address
cannot be offset in the forward direction.
The Input Relay Offset parameter is used when the function code is 02 or 4341 hex. The address is offset
by the long-word offset in PARAM22 and PARAM23.
Register Type Value Type Remarks
0 M Sets the target data type to MB for bits and MW for words.
1 G Sets the target data type to GB for bits and GW for words.
2 I Sets the target data type to IB for bits and IW for words.
3 O Sets the target data type to OB for bits and OW for words.
4 S Sets the target data type to SB for bits and SW for words.
5 or higher − Not used for the Extended MEMOBUS protocol.
Do not change the value of PARAM19 from a user program or by any other means.
