Process data and status information
108147_en_00 PHOENIX CONTACT 19 / 44
Channel status The channel status is transmitted in a bit and corresponds to the current status of the re-
spective channel. A 1 corresponds to the "on" state; a 0 corresponds to the "off" state.
Error status The error status is transmitted in a bit and corresponds to the current error status of the re-
spective channel. A 1 means that the corresponding channel was switched off after an error.
A 0 means that no error exists. Switching on a channel that was switched off by an error re-
sets its error status to 0.
Load current channel The load current at a channel is encoded in one byte. The value range 0 ... 255 corresponds
with a gradient of 0.1 to the value range of 0.0 A ... 25.5 A.
Input voltage The input voltage of the CBMC E4 ... IOL is encoded in one byte. The value range of 0 ... 255
corresponds with an offset of 10 V and a gradient of 0.1 to a representable voltage range of
10.0 V ... 35.5 V.
The process data is also available via acyclic access (see Section "Acyclic data" on
page 20)
