Now I have only one module mounted on rack 0 to test but the indication still at rack 1 and I can not connect (as to download hardware configuration) and programming I have tried to mounted this module on rack 1 but it doesnt not allow me to down load OB1 and go online with the other FB. FC.OBs etc as i still search for RACK 0 connection Is there anyway i can reset this module to RACK 0 and re download all program to do the testing? Is there any physical setting for this ?

Use the switch on the rear of the CPU to set the rack numbers. Best regards. H-H
