Chapter 2 Writing Programs
Minotring devices
It is sometimes inconvenient for users to search for devices in a logic program that the users test, and
change the values in the devices because the devices are in different sections of the logic program.
Besides, sometimes the purpose of modifying the values in devices in a program is not to debug the
program, but to test an external device. If the users want to change the values in devices in a program by
monitoring the program, they may not easily find the devices, and they need to have the program. To solve
these problems, the users can use a device monitoring table. If the users change the values in devices in a
program by means of a device monitoring table, they do not even need the program.
The users have to click
, and then double-click the device monitoring table which appears.
After the users type a device name and the number of devices, and click
Input
in the
Device monitor
input
window, devices will be brought into the device monitoring table.
