B–10 EPM 2200 POWER METER – INSTRUCTION MANUAL
MODBUS REGISTER MAP APPENDIX B: MODBUS MAPPING FOR EPM 2200
3
Register valid only in programmable settings update mode. In other modes these registers
read as 0 and return an illegal data address exception if a write is attempted..
4
Meter command registers always read as 0. They may be written only when the meter is in
a suitable mode. The registers return an illegal data address exception if a write is
attempted in an incorrect mode.
5
If the password is incorrect, a valid response is returned but the command is not executed.
Use 5555 for the password if passwords are disabled in the programmable settings.
6 M denotes a 1,000,000 multiplier.
7
Not applicable to EPM 2200
8
Writing this register causes data to be saved permanently in EEPROM. If there is an error
while saving, a slave device failure exception is returned and programmable settings mode
automatically terminates via reset.
9
Reset commands make no sense if the meter state is LIMP. An illegal function exception will
be returned.
10
Energy registers should be reset after a format change.

All 3 voltage angles are measured for Wye and Delta hookups. For 2.5 Element, Vac is
measured and Vab & Vbc are calculated. If a voltage phase is missing, the two voltage
angles in which it participates are set to zero. A and C phase current angles are measured
for all hookups. B phase current angle is measured for Wye and is zero for other hookups. If
a voltage phase is missing, its current angle is zero.
15
If any register in the programmable settings section is set to a value other than the
acceptable value then the meter will stay in LIMP mode. Please read the comments section
or the range for each register in programmable settings section for acceptable settings.
