2.10 Communications with a JTEKT PLC (TOYOPUC Protocol)
Message Functions
2-314
 Offsets (PARAM20 to PARAM27)
These parameters set the offset for the data address in the MP3000.
The MP3000 will offset the address by the number of words specified by the offset.
Note: An offset cannot be a negative value.
Offset parameters are provided for each of the target register types.
The following table lists the offset parameters.
 Data Relay Offset (PARAM28 and PARAM29)
These parameters are not used for the TOYOPUC protocol.
 Data Register Offset (PARAM30 and PARAM31)
These parameters are not used for the TOYOPUC protocol.
 Output Coil Offset (PARAM32 and PARAM33)
These parameters are not used for the TOYOPUC protocol.
 Output Register Offset (PARAM34 and PARAM35)
These parameters are not used for the TOYOPUC protocol.
 M Register Writing Range (PARAM36 to PARAM39)
These parameters set the allowable address range for write requests from the remote station. An error will
occur if the write request is outside this allowable range.
Specify the M Register Writing Range (PARAM36 to PARAM39) with word addresses.
Note: 1. M registers are always used as the destination in the MP3000 for data write requests from the remote station.
2. The writing range parameters allow you to specify the range of M registers that messages are allowed to write to.
The following table lists the writing range parameters.
Set the writing range so that it satisfies the following condition:
0 ≤ M register writing range LO ≤ M register writing range HI ≤ Maximum M register address
