Chapter 7 Application Examples
Note:
You can assign existing program variables or create IO variables for module channels in the
"Variable" column as shown in the red box above.
When the module channels are not assigned any program variable, the I and Q devices in the
7_
"Address" column are valid, and you can directly operate the I and Q devices in the program to do
the read or write operation to module channels.
After the module channels have been assigned program variables, the I and Q devices in the
"Address" column are invalid, but you can do the read and write opertion to each channel through
the variables in the program.
For example, when no module channels are assigned any variables, write 255 into the %QB1
device to change all the local output points of ASRTU-EC16AP1TA to ON and then monitor the
status of the local input points of ASRTU-EC16AP1TA through the %IB4 device.
To change output points 0~7 of AS16AP11T to ON, write 255 into the %QB2 device in the program.
To make each of channel1 ~ channel4 of AS04DA-A output the 5V voltage, write a 16000 in each
of %QD1~%QD4 devices in the program, and then read the channel1~channel4 analog conversion
values of AS04AD-A through the %ID4~%ID7 devices.
6.
If you need to modify the modes for AS04DA_A's channel1 ~ channel4, please add corresponding
CRs for the modes of channel1 to channel4 into the Startup Parameters of ASRTU-EC16AP1TA.
For more information about startup parameters, please refer to Section 5.5.
