E.5. UPS Parameter
Standard UPS – Address Description
Please note that this is just an example for a typical UPS, not every UPS has all these values,
some UPS may have more, some less. Please contact your UPS manufacturer to check which
variables are available and which requests are not supported.
Note: “Type U/S”: this defines whether the answer has an algebraic sign (math. +/-) or not. U
means “unsigned”. S means “signed”, this answer may be positive or negative.
Some clients (e. g. MODBUS Poll) use “MODBUS addresses” with a valid range of 0-
65535, but some other clients use the “MODBUS register” with a valid range of 1-65536. In this
case it is required to add a “1” to the MODBUS address you want to poll.
If you are using a PILLER UPS with a CS121 firmware version 4.29.3 or higher,
please take a look into the UPS user manual for the accordant MODBUS values. If you are
using a BACS system at the same time, no BACS values will be available via MODBUS.
