 Input Register Offset (PARAM24 and PARAM25)
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 Register Offset parameter is used when the function code is 04, 0A, 4346, 4349, 434D, or 434E
hex. The address is offset by the long-word offset in PARAM24 and PARAM25.
 Hold Register Offset (PARAM26 and PARAM27)
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 Hold Register Offset parameter is used when the function code is 03, 06, 09, 0B, 0D, 0E, 10, 4346,
4349, 434B, 434D, or 434E hex. The address is offset by the long-word offset in PARAM26 and
PARAM27.
 Data Relay Offset (PARAM28 and PARAM29)
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 Data Relay Offset parameter is used when the function code is 4341, 4345, or 434F hex. The address
is offset by the long-word offset in PARAM28 and PARAM29.
 Data Register Offset (PARAM30 and PARAM31)
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 Data Register Offset parameter is used when the function code is 4346, 4349, 434B, 434D, or 434E
hex. The address is offset by the long-word offset in PARAM30 and PARAM31.
 Output Coil Offset (PARAM32 and PARAM33)
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 Output Coil Offset parameter is used when the function code is 4341, 4345, or 434F hex. The address
is offset by the long-word offset in PARAM32 and PARAM33.
 Output Register Offset (PARAM34 and PARAM35)
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 Output Register Offset parameter is used when the function code is 4346, 4349, 434B, 434D, or 434E
hex. The address is offset by the long-word offset in PARAM34 and PARAM35.
