 Posted: 28/09/2018 12:47 Post subject: M221 PROBLEM WITH I/O EXPANSION BUS |
 |
|
Hello!
I am using PLC TM221CE16R and SoMachine Basic v1.6. My PLC has firmware 1.6.0.1. I use analog expansion bus, input module TM3AI8. Everything was working fine for 2 hours until suddenly I got next message in SoMachine Basic: I/O expansion configured but is absent or inoperative. I/O expansion bus is not started.
Since then ERR LED is always blinking. I already tried deleting program, updating firmware, removing expansion module in configuration page, removing/adding physical module, selected module as Optional, removing battery - nothing helped. If I try removing application, ERR LED is still blinking. Seems like I can't delete previous program, something like config file is burned into PLC.
Can anybody please help me? It is really frustrating.[url=http://www.99poze.ro/p/33e2aa2086d212e55834ef9267aae0b8.jpg] [/url]+[url=http://www.99poze.ro/p/a7a71dd2f63f75db42f2d7489d6a2380.jpg] [/url]+[url=http://www.99poze.ro/p/4302ea42402209adf3a1c9bde3502f27.jpg] [/url]+[url=http://www.girlshare.ro/3490179963.6]EXPANSION+BUS.PNG[/url] |

Ok, I understand all that. But why is there a problem? I assembled everything correctly, everything was working. But suddenly stopped working. Nothing was reconfigured or removed. May there be any other solution?
@mikoian, anyway thanks for reply. |

| After a month and with help of technical support we figured out that problem was with hardware on PLC. They sent me new PLC. Thanks for help! |
