VREF error on XC43 Enable

jolynik 2 months ago in Expansion modules / XC4x updated 1 week ago 10

Working on a project in which 2 XC43 modules are not supplied with power until the MD4 commands a safety relay contactor closed.

I've worked through almost all the bugs, but I'm getting a VREF A error as soon as the XC43 modules enable. I've tried leaving up to a 30 second delay after powering the XC43 modules to enable them, but the error still pops up for one cycle and then shows up on screen (Watching in a measure group, VREF starts at 0V for one or so cycles, then goes right to 5V). All the sensors read fine, just have the error at system start.

Is there any way to delay how long it takes for the VREF error to show


xc43 referance voltage

On the XC4x serie there are multiple Vref+ and Vref- and on both C1 and C2 

Are these interaly connected in the module? 

Or are they seperate from eachother and serve only dedicated Vin's?

Best Regards Ed


PWM OUT HS to control proportional valve "D1FBE01HC0NJJ3"

Hassan 9 months ago in Expansion modules / XC4x updated by Gustav Widén (System support) 9 months ago 2

I'm using the expansion module XC43 to control valves, usually, I use Cout to control proportional valves but I run out of current output pins " I have 13 valves" I'm wondering if I can use PWM OUT HS to control D1FBE01HC0NJJ3 " Proportional directional valves in general " also L90LS, P70? Because it seems for me that PWM is only to control pulsar valves that have some frequency working value.  


Expansion Module CANBus

Greg R 1 year ago in Expansion modules / XC4x 0

Our usual setup is an MD4 with an XC4X expansion module. But we end up using an MC4X because we need the CANBus available on the master module. It would be nice if the expansion module provided access to additional CANBus the same way it provides access to its IO.
