APPENDIX E: MODBUS
FUNCTION
See page 28 APPENDIX A: DISPLAY
SETUP for Setup.
OPERATION
The S7800 ModBusTM Data Feature
enables terminal 1, 2 to Data + and Data -.
Table 16 provides register mapping. It
identifies the mapping of the 7800 SERIES
parameters to ModBusTM registers.
Function Codes
Supported function codes of Modbus
Protocol Reference Guide (PI-MBUS-300
Rev. J) are 3, 4, 6, 16, and 17. Function
codes 3 and 4 are treated the same by the
S7800. Two registers should be read when
the data format is a U32 value (4 bytes); if
both registers are not read, then data for a
part of the value is returned. U32 values are
either in Big-endian or Little-endian format.
