Near miss on the cartoner last night and I want to understand it before I touch any code. An operator was jogging the infeed servo from the PanelView Plus 7 when someone pulled the Ethernet cable at the panel to plug a laptop in. The axis kept jogging for about eight seconds and ran into the end of travel switch, which stopped it. Nobody hurt.
CompactLogix 5069-L320ER, Kinetix 5500 on the infeed, Studio 5000 v33. The jog is a momentary push button on the HMI writing a BOOL, and the PLC jogs while that BOOL is 1.
I checked the button, Set on press, Reset on release, then pulled the cable myself on a test run and it just carried on jogging. Nothing has changed on this line, the code is two years old.
Is this the button hold time? Could someone explain what's meant to clear that bit?
What's the jog velocity, and is there a hold time set on that button? Some people set a hold time of a few seconds so the press registers, and that'd keep the bit high after release. Also which firmware on the PVP7 and what's the coarse update period on the motion group, just to have it.
