sir,

i had connected two premium tsx57353 having ety4103 module on ethernet protocol.

the communication was established and i was able to ping the other premium.

i would like to know how to read the memory word from one premium to the other. i had tried using read_var command...

one more problem i faced was i was not able to enter the ip address nor mac address in i/o scanning page...

kindly help me in the same.

 

Use IO Scaning. Use "Capital" letter.

 

You are talking about two different ways of communicating over Ethernet.

READ_VAR & WRITE_VAR ars ujsed as messages. You noly send them as an when you ladder logic calls them . IO scanner reads, or writes continually.

IO Scanner setup

I think the problem is a bug in PL7. You have to use your 'number keypad', not the normal numbers at top of keyboard. This means if using a laptop you must use the function key, as a shift key to insert numbers for the IP address.

Mesgaging - READ & WRITE_VAR

You need to create a 'look up chart' or cross reference. You have to setup an IP address, and also an XWAY address. In the READ & WRITE VAR you then enter the XWAY address. Example of READ_VAR

READ_VAR(ADR#{1.2}SYS,'%MW',100,10,%MW200:10,%MW210:4)

Number in brackets is XWAY address of device you want to communicate to.

Hope this helps. Let me know.
