MC43 DOUT HS&LS max load per group
What are the group numbers for these outputs? The manual doesn't list them in appendix A?
Invalid application MC43
Hello,
This happens in a system with just an MC43, and no other connection than Ethernet.
Same hardware and software without problems on previous machines.
After successfully sent the project to the system (through Ethernet, and from IQAN Run or from IQAN Design ), when trying to go online the following screen appears:
(from IQANDesign 5 Latest version, after trying to go online)
(from IQANRun 5.01, after trying to get system info,or enter Adjust, or whatever)
It seems the module lights blink the following way:
4xRed,
2xYellow + 2xYellow + 1xYellow + 3xYellow
All short blinks...probably.
Any hint?
Thanks a lot.
3 wire 0-20mA sensor input on MC4x
The installation manual states an example for a 2 wire 0-20mA input into the controller, but there is no reference to a 3 wire input. Are these supported? I'm assuming it will be the same connections just the sensor ground (which does not include the signal) will go to chassis or vref -ve? Can anyone confirm?
LED lamp and how is it controlled it via the program
where on the MC41 I connect LED lamp and how is it controlled it via the program
PWM Driver 5A
Has anyone had any experience whereby they have used a single IQAN PWM out with a 5A load ? The data sheets say "no" but I am just wondering if this is possible if the number of outputs used simultaneously, is controlled.
MC41 PWM out HS+LS flyback diode wiring question
I have a MC41 setup where I need to use a bidirectionnal CAM output in PWM mode to drive a bidirectional valve (2 coils). There is a mention to not use a flyback diode in closed loop control but is it ok to add diodes on coils if the outputs are used in PWM mode, not in current output? I tried it and it seems to work just fine.
I want to add diodes as there will be an emergency operation switch installed to directly power the coils. We want the diodes to prevent high voltage spikes to the MC41 module and the switches.
Found on the forum:
With IQAN-MC3 and IQAN-MC43, -MC42 and -MC41, the internal clamping diode is not disconnected when COUT pins are used as open control PWM.
Does that mean that we do not need to add diodes?
MC43 RTC
Does the MC43 have a Real Time Clock? Does it need one?
Ethernet Communication Port
With the new MC42 and MC43 master modules, I see you have the ability to communicate via Ethernet communication port. Where can I find this part?
