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

We've used IQAN modules extensively in our equipment and we've always mounted the modules in an electrical cabinet. We prefer the entire IQAN system to other PLCs that would normally be used in a cabinet, but we could really benefit from an IQAN module that was more industrial style, i.e. that it would have screw terminals that were easy to rearrange, add, remove, etc.

Has anything like this been considered before? Anyone else with this need?

I am trying to read a NTC thermistor with a resistive output ranging from 810 - 76.9 ohms on the MC43. 

In the past we have used a voltage divider circuit to read the sensor value on a VIN channel, but if the MC43 could introduce a bias current to the thermistor then the output voltage could read without the need for a second resistor in the mix. 

I did not seeing any mention of this in the MC43 manual but was wondering if anyone has faced this challenge before. 

Thank you. 

Could you advise if there is a replacement for the 5010001 ?

I have a defective module on my   SMV SC4542 TA5 and I can not find a replcement

could you assist me ?

I am trying to control a valve without over speeding the pump. What would the MR values need to be? Does 100% command at a 100% Max MR value equate to the source voltage, in this case 24VDC? See coil characteristics below. 

Hi all.

I'm looking to obtain a set of id tags. I'm only looking to run 5 modules. Is there a way to just buy a set of singe tags0-7  without having to buy box's of 10 of each that I will never use?

Thanks

Hello,

We are currently working with a MC43, and I had a question regarding the use of PWM out as a control device. I found this post, since it was 4 years old thought I would ask again. We are trying to control a water valve position with one of the PWM out on the MC43, but not getting the expected results. 

The datasheet specifies a leakage current of 2mA. What do you recommend to clean this up and bring it down close to 0?

I am relatively new to the whole IQAN infrastructure and I am wondering why is there such a high leakage current? Is there any benefit to it?

Thanks in advance

Is there a chart comparing controller performances other than just I/O counts such as Memory size/ processor speed.

Specifically I am looking to decide what is the next platform we are going to use.  I am looking for a Non display master with large number of Can interface.  So MC43 comes to mind but in thread I read it does not seem to be as powerful as the MD4 display series.
