A1.5 Setting The Di Function Block - YOKOGAWA Admag TI Series User Manual

Resetting or presetting totalized value
„ „
Reset totalization
Access the OP_CMD_INT parameter in IT block, and set Reset "1".
Preset totalization
(1) Access the MODE_BLK parameter in the IT block and set Target (target mode) to O/S or
Man in.
(2) Access the OUT parameter in the IT block, and set preset value to "Value".
(3) Access the MODE_BLK parameter in the IT block and set Target (target mode) to Auto.
A1.5 Setting the DI Function Block
The DI function block receives and outputs limit switch signals from the transducer block.
Three DI blocks have independent parameters. Set up the parameters of each DI block you use,
individually as necessary. The following shows setting examples of the DI1 function block.
Setting the channel
„ „
Specifies the limit switch number of the transducer block to be input to the DI block. For details,
refer to Section 5.3.
Setting the damping time constant
„ „
Access the PV_FTIME parameter. Set a time to damp. (in units of seconds)
Simulation
„ „
Perform simulation of each DI function block by setting the desired value and status of the input
to the block. Access the SIMULATE_D parameter and change the values of its elements as
follows.
(1) REMOTE LOOP TEST SWITCH is written to the SIM_ENABLE_MSG (index 2922)
parameter of the MTB.
(2) Access the SIMULATE_D En/Disable parameter. Set the simulation active or disable.
2 :
1 :
(3) Access the SIMULATE_D Status parameter. Set the desired status code.
(4) Access the SIMULATE_D Value parameter. Set the desired input value.
When valid, the DI block uses SIMULATE_D Status and SIMULATE_D Value as an input, and
when invalid, the DI block uses Transducer Status and Transducer Value as an input. Refer to
"Simulation Function" in Section 5.13.
