Simulation Function

The product has a function to simulate the input of the function block as if the data is received
from the transducer block. This function makes it possible to test the function block and alarm-
processing system on the downstream side.
To prevent this function from being mistakenly activated while running, a simulation switch is
implemented as a "key" on the amplifier. If this switch (SW1-1) is moved to the ON side, the
simulation is enabled. (See Figure 13.1.) If SIM_ENABLE_MSG of the maintenance transducer
block (index 2922) and REMOTE LOOP TEST SWITCH are written in order to do the same thing
from remote, it activates the same operation as when the above switch is turned ON. However,
the value of this parameter is lost when the power is turned off. An alarm occurs from the
resource block in a state where a simulation is possible. After use, swiftly prohibit simulation.
This function can be configured with the following parameters.

If "2" is set to Simulate En/Disable, the relevant function block starts using the simulation value
which is set to this parameter instead of the data from the transducer block. It can be used
for propagation of the status to the subsequent block, occurrence of the process alarm, and
operation test of the subsequent block.
