  1. Can somebody tell us what is acceptable signal quality? For example, is SI 185 (in V120) value 18 acceptable quality? In what range are the signal quality values? Thanks!
  2. Solved, Protocol Config FB had to be disabled. Noted that SI115 was 2 (FB protocol) instead of 1 (Modbus). Thanks.
  3. I can not activate modbus in V570 via GSM. I am using same software routines that work fine with V120. Modem initialises fine in COM 1 (sb80=1), modem also connects fine when connected/called from modbus polling software (SB 86=1). However, the modbus traffic doesn't initiate. The polling software says "Connected" and then "Modbus request failed". Modem status in PLC (SI 80) lays with value 2. When connected, the value is 4, then chages to 1, then back to 2. The polling software should be fine, it activates modbus OK with V120. So there may be some software problem in my V570 ladder code, even it works in V120. Same modems and cables are used and V570 com port dips are in RS232. What can prevent modbus traffic from being activated. I have used the Modbus config, SCAN, SCAN_EX and Porotocol config function blocks but looks like I must be doing something wrong - even they work with V120. All ideas greatly appreciated!
  4. I have lost my original (rather large) .vlp project files (laptop stolen). From email sent folder I still have the download files (.UDC and .DVI) Now I know the whole point of creating these download files is to restrict access to the original file, but I still would like to know if there is ANY way or utility to save the original editable .vlp file ? This is two weeks work blown in the wind:(
