Temperature module inputs

Description
SIMOCODE pro has a "TM Inputs" function block with three analog sockets
corresponding to the three sensor measuring circuits of the temperature
module. The temperature (in K) of the three measuring circuits can be read
from these sockets and processed internally. An additional analog socket
always supplies the maximum temperature of all three measured
temperatures. Furthermore, the two binary sockets of the function block
represent the status of the sensor measuring circuits. The temperatures can
be processed internally and/or transmitted cyclically to the automation
system via the "Cyclic Send" function blocks.
Note
The "TM Inputs" function block can only be used if the temperature module
(TM) is connected and configured in the device configuration!
