10.3 Simulation Function
The YVP110 has a function to simulate input
signals to its internal function blocks and makes the
blocks to carry out the specied actions with the
simulated input signals in order 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 modied during
plant operation by mistake, a hardware switch
labeled SIM.ENABLE is provided on the YVP110’s
amplier assembly. Sliding this switch position
to ON enables the simulation function to run.
Remotely writing “REMOTE LOOP TEST SWITCH”
to SIM_ENABLE_MSG also causes the same
effect as turning ON the SIM.ENABLE switch;
however, the value of SIM_ENABLE_MSG will
be lost when the power to the YVP110 is turned
off. In short, simulation can be carried out if the
hardware SIM.ENABLE switch is ON or if the value
of SIM_ENABLE_MSG is “REMOTE LOOP TEST
SWITCH”.
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 nished.
