Technical support / Warning: No Response from PLC
« on: October 02, 2008, 05:45:36 PM »
Hello,
I'm not sure what I am doing wrong, but I cannot get the PLC to communicate with my computers. I've tried it with the regular cable and using the USB Serial converter. With the standard cable I only have COM1 available as an option. With the USB I get COM1 and COM3.
I've changed the Baud Rate down to 9600 on all ports. Changed it back to 38400. Flipped the dip switch #4 to on, powered back up, changed it to 9600 and still get the same error.
I don't have anything loaded on the PLC as it's never communicated with the computer. I've tried it on an XP and win2000 machine. PLC is a T100MD888+.
Power Supply is EGS Sola/Hevi-Duty Linear DC power supply SLS-24-024T, with 24 V output. - is connected to the - on PLC and to the 10A ground.
During normal power up all three lights on the right power up, then the bottom two turn off and the top green one stays on. With Dip#4 ON the 2nd red light is on.
