Hi,
my name is Luciano, and I write from Italy.
I'have a problem with Wago PLC 750-841.
I make a programm error and the plc go in allarm!!!
I have reset the power of plc, and when it restart is impossible to go online!!!
The plc have lost the IP adress and is also impossible to go online whit the wago serial cable.
I try also to connect with the software WAGO Ethernet Settings (V03.00.06) setting the default parameter of comunication (com1 19200 even 8,1) but is impossible to connect!!!
I try to reset by pressing the switch button pf the PLC, but is impossible to comunication.
When I turn ON the PLC the led make this sequence:
1--> I/0 and USR make one lamp red
2--> I/O flashing about 3/4sec orange color
3-->Link and TXD/RXD go on (green colour) for about 0,5 sec then turno OFF
4--> MS go on and stay on (green colour).
I have also modification the phisycal configuration (i put on PLC more I/o) but the led of plc works always in the same mode!!!!!!
Is possible to make a reset hardware of the PLc??
I can try to download again the firmware ??? How??? Where I can found the firmware of this PLC???
Thanks very much....in Itali The Tecnical of Wago is in holliday, and i have a very big problem......
thanks again
