Magnet serial timeout
When a serial timeout arise it means that there is a problem in the communication between the devil and the magnet device. The actions to perform in this case are:
...
The DCS Element dashboard shows if there is some moxa involved in the connection if it's the case . If this is the case a check of the full SW/HW stack must be performed:
- check the integrity of the cabling from the port of the moxa (found in DCS Element dashboard ) to the magnet interface.
- With the corresponding devil running check if the TX led of the port is blinking (the devil tries to access the hw).
- If not, you must to check if the devil is running and Moxa serial lines documentation is aligned with the DCS Element dashboard.
- access to the Moxa web interface interface and navigate in Monitor→async and look the debug information of the relative port (see the picture below). Here there are the byte sent by the devil (TX) and by magnet (RX). If the communication between the devil and the moxa is ok the TX number should increase as well if the communication between the magnet and the moxa is ok should the RX should increase. Remember the page is refreshed each time a click on 'Async' is performed. Each time the RX/TX led blinks the counter should increase.
- If the RX led of the corresponding port port is not blinking means that no data are coming from magnet
- To test if the full stack HW/SW till the magnet use a loopback cap (il tappo). You should observe TX/RX blinking and the counters of the moxa interface increasing. If this is the case means the serial interface of the magnet must be repaired or replaced.
