My Symax 400 plc does not run when I switch from "halt" to "run". Can anyone help? First question is - - do you have programming software? Without it there is no way Im aware of you can tell. If you do have the software there is an error code on the online/status mode screen once online with the processor. ALso, on the same screen how many rungs does it show your program has? Another place to look at is register 8176 in data mode, is bit 3 set? That will prevent it from going online. What software package are you using if you have it, I can then point you in other directions. I do have the Symate Plus software for Symax 400 plc. I can send programs to the plc processor. At first, the message was "overflow error" and then the problem of not being able to switch from "halt" to "run" occured. The "overflow" problem is now cleared up. I am able to go "online" but still unable to set the processor in "run" mode. Perhaps I should check out register 8176 bit 3. If I reset it, does it mean I can switch it to "run" mode? Once reset, go ahead and try to go to run mode. If it fails, there should be a corresponding error code on the main screen -- what is it? Thank you. Ill try it out later when I am at the shop-floor and inform you of the outcome I have managed to set the plc to "run" mode. However, when I download a simple 1 rung program with input as 5.02(push button switch) and output as 1.02(solenoid valve)the plc does not give any output nor is the input activated when the push button is pressed. The plc has been set to "run" mode. Kindly help! Thank you. |
