Parallel Functions in MC5-IS
This chapter explains what kind of simultaneous tasks you can do
with MC5-IS.
Every module in MC5-
IS may simultaneously
have their own tasks.
Also, the RS232 con-
nector may have its
own independent task.
The ET module has a
double action ability:
When one of the sen-
sor measure & gener-
ate section terminals (T/C INT RJ, T/C Low V, or R,RTD terminals)
is used for measuring purposes. Then an electrical output signal
may be generated from the ET module’s output terminals. This
feature is not available when generating a signal from the sensor
measure & generate section terminals.
The ET module is also capable of doing the following double tasks:
• Measuring Low Voltages or thermocouples (connected to any
terminal used when measuring thermocouples) and at the
same time either measuring or simulating an RTD with the
RTD sensor terminals.
• Generating Low Voltages or simulating a thermocouple (con-
nected to any terminal used when simulating thermocouples)
and at the same time measuring with the RTD sensor termi-
nals.
Warning!
There is no galvanic isolation between the ET module’s measur-
ing terminals and generating terminals.
