Chapter IV Instruction of HMI Module
4.1 The difference between LCD message of SR and the traditional LCD message
In traditional LCD, it can only display some fixed and simple message such
as time, I/O status etc. It cannot display the counter value, timer value and analogue
value. And all the LCD message screens is set and programmed by the program
engineer, so users cannot change, add, or remove any message screen. And the
operation of the traditional LCD message screen is not easy to use for the end user.
Regarding the above shortcomings of the traditional HMI module, we have
adopted a new method to develop the SR, and offer to user a free, and easily LCD
instruction, the powerful function of the LCD is as follows:
1. Providing 64 Human-Machine Interfaces
When using SUPER CAD, users can add HMI according to the demand no more than
64. And the non-alarming interfaces can be seen on LCD panel.
Fig. 4.1
2. Providing Several HMI Module
When you add an HMI, the system will create a referring module screen according to
the connection relation, so user just need to make some minor changes on the HMI,
for example as follows:
Note: B0 block is a CMPR instruction, and it has an SLCD as L:0, connect the under
output leg of B0 to the under leg of L:0,
Double click the L:0, it will create the following left screen.
Created screen automatically After minor change
