9.3.3 Transmit process values of the completeness monitoring via TCP/IP
The device can transmit the process values to a PLC via the TCP/IP protocol. The process values are
displayed in the ifm Vision Assistant as output string as below:
In the output string the process values are separated by a semicolon. The output string is transferred to a
PLC in the displayed sequence.
Observe the following remarks for the transmission of the output string to a PLC:
●
Semicolons ";" in the output string are not transferred.
●
All numerical values are converted into binary 16-bit integers before the transmission.
The output string is composed of the following (data type: ASCII):
