Simulation Function
The FVP110 has a function to simulate input signals to its internal function blocks to
make the blocks to carry out the specified actions to allow for testing applications in the
host computer or alarm handling processes. Each function block has a parameter to
switch on/off the simulation function. To prevent this parameter setting from being
modified during plant operation by mistake, a hardware switch labeled SIM.ENABLE is
provided on the FVP110’s amplifier assembly (Figure 55).
To engage this function:
❑ Slide the switch position to ON.
or
❑ Remotely write REMOTE LOOP TEST SWITCH to SIM_ENABLE_MSG.
However, the value of SIM_ENABLE_MSG is lost when the power to the FVP110
is turned off.
When the simulation can be carried out, alarms generated from the resource blocks
mask the other device alarms. Hence, simulation must be disabled immediately after it
has finished.
