Example 2: Timer/Counter present value Compare
The Comparator instruction can be used to compare Timer, Counter, or other function values to a constant value or each other. In this example
below, Mode 5 is the selected function that compares the value of Counter (C01) with the value of Timer (T01). Status coil G01 turns ON if
present value of C01 is not less than present value of T01.
HMI DISPLAY INSTRUCTIONS
The LRD includes a total of 31 HMI instructions that can be used throughout a program. Each HMI instruction can be configured to display
information on the LRD 16_4 character LCD in text, numeric, or bit format for items such as current value and preset value for functions,
Input/Output bit status, and text. There are three kinds of text in HMI. They are Multi Language, Chinese (fixed) and Chinese (edit), Multi
Language is shown in the adjacent example. Each HMI instruction can be configured separately using the Edit>>HMI/Text menu selection from
the LRXSW software. In the adjacent example, HMI instruction H01 is configured to display the value of T01, and some descriptive text.
Allows the SEL button on the LRD keypad to activate the selected message on the LCD even the Hxx is inactive.
A phone number can be displayed on the screen to alert an operator to call for help. But the phone number field does not dial a modem or allow
for a modem connection.
Each HMI instruction has a choice of 2 operation modes. The table below describes each configuration parameter.
