Appendix C – Modbus Register Numbers

The following tables list all of the PF2100 Register Numbers that are accessible via the Modbus Card interface.

Discrete Table

The following registers are all 1-bit in size and are read only in the current firmware version. A future firmware revision may enable some of these to be

writable.

Values

10001

RUN

0 = OFF

10002

Pilot

0 = OFF

10003

Low Fire

10028

Low or High voltage

0 = Voltage OK

10029

0 = No Alarm

Analog Tables

The following registers are all 16-bit in size and are read only in the current firmware version.

The registers are all mirrored between two different tables (the 30000 Input Register Table and the 40000 Output Holding Register Table). It has been observed

that some PLCs do not allow bit masks to be applied to some tables but do allow it on others. This is the reason for mirroring the registers between two tables.

A future firmware revision may enable some of the 40000 series registers to be writable.
