PRO-FACE ST401 connection problem

[psion]

I'm trying to connect Proface touch panel ST401 to T100MD+888.
ST401 supports RS-232C.
I set MODBUS Slave, 38400, 8bit data, 1stop bit, no parity.
I made a keypad input display on the screen and assigned memory address as 401101 in GP-PRO ver7.01 software.
I expect I can see the input value in the on-line monitoring window of your TRiLOGI program when I input a value on the touch screen.
I expect DM[1100] will be set as the value I input at 401101 on the screen. Am I right?
But I can't see any changed values even if I watched all the DM[] registers.
Please help me .... I don't have much time.

The data memory in the T100MD+ PLC maps to MODBUS address 41001 to 45000. So if you want to map to the Data memory, associate a variable in the touch panel to any of these addresses and what you enter on the touch panel will be shown on the online monitoring screen at the corresponding DM address.

Dear,

I understand your explanation and I thought I did that.
One thing I can't understand is the memory address is 5 digits in my proface program.
Your modbus address is 4 digits excluding '4' which means the holding register.
I think it's because of the memory extension.
So I assigned 4 1001 as 4 01001.

Please help me....

Is it that they are refering the address as bit address? Some system refer the bit addresses as 40001.1 to 40001.16, then 40002.1 to 40002.16 etc. If that is the case then these addresses are not the word addresses. You should be able to define the word addresses for objects that can be represented by 16-bit word, not objects such as push button that can only be represented as bit address.

They surely are word addresses.
Bit address goes like 4 xxxxx 01
I can send the image captures for this setting if you give me your email address.

You can email to support@tri-plc.com although frankly this is a problem you will have to ask Proface tech support for answers. MODBUS addresses are five digits for holding register. Maybe you can try 410001 for DM (assuming that Proface got it wrong and added an extra 0.)
