Phoenix Contact CBMC E4 24DC/1-10A IOL - Bit-Assignment of Data Type Output Voltages

Process data and status information

Output voltages
The output voltages of the channels can be retrieved via Index 3333
dec
. The voltages of all
channels together are stored under Subindex 0 and are returned in 8 bytes. Each channel's
output voltage is encoded in 2 bytes.
Example:
With Byte [0] = 01
hex
and Byte [1] = 2B
hex
, the result is the 16 bit value 01 2B
hex
. This cor-
responds to the value 299
dec
. The voltage value comes from multiplying the 16-bit value by
a gradient of 0.1. This results in an output voltage of 29.9 V.
The individual voltages of the channels are reached under Subindex 1-4.
