We have now released the first two variants in the IQAN-MD5 family, the 5" and the 8" variants.

You'll need IQANdesign 7.02 to use these, which also is available.

Product information are available on parker.com.

Would be nice for MD4 displays to have day/night mode where background and text properties would change without the need of creating extra layers. 

Hardware Question:

In the Documentation for the MC4x family of controllers - it says in many places to use diodes for external coil suppression, for example when driving a relay with the Digital Out HS driver from the MC4x.

A relay that I have specific to my application requires (highly recommends) the use of varistor coil suppression, which is less "harsh" on the relay device during transients. The specification requests a clamping voltage of 3x the coil voltage, i.e. 36Vdc for a 12Vdc relay coil.

Are there any adverse affects of using a varistor instead of a diode for coil suppression? 

Perhaps this could be also compatible with the hardware design of the MC4x series of controllers?

(Hint: I already have tested this configuration on my system to many thousands of cycles under load with no discernible affect on system operation or relay operation)

This module supports alot of IO and 5 x CAN. Very simple functions to serve all of the IO and CAN easily burn the available resources and I am wondering if there are any upgrade plans ?

The new -M24 versions are now in serial production:

IQAN-XC4x_brochure_MSG17-8417-UK.pdf

Requires IQANdesign version 7.03, see Version 7.03 released / Software / IQAN

The electrical diagrams for the MD5 that are published on the Parker website have an error, the +batt and -batt are reversed on those drawings. The MD5 instruction book is correct.

i need more output io

but it looks like a big tear up

I'm hoping someone might be able to chime in if they have seen something similar before.

I'm driving two contactors (they close at different times) off the MC41. The contactors at peak draw 3.9A for about 75ms. When the contactors close, a very short time later, the MC41 enters a critical fault. The flashing lights (4R, 1Y, 12Y, 3Y, 1Y, 2Y) seems to indicate there is a 'watchdog' fault. Looking at my CPU/RAM usage and cycle usage, we are not even using 1% capacity. Is it possible this overcurrent condition could trigger this particular fault?

As well, I can't seem to find any information on what the 12Y is supposed to mean? "R4:1 n:3:1:2" which would be the "n" in the manual. What would the 12th part of the software mean?

Hi!

Previously we used MC2 in a project. Now changed master module in the program to MC43.

We have a DIY test board (large resistors with LED for indication) to double check if the machine sends signal to valves etc.

Using COUT channels...so connectors come in pairs. With MC2 if one of the connectors wasn't connected to a load it would display "open load" error when machine would send a signal to a valve that isn' t connected, but connected one would work when output is signal is given. (no open load error when joystick is in neutral)

Now with MC43- both COUT pair connectors have to be connected for it not to display "open load" error..even when joystick is in neutral position.

Is this because MC43 diagnoses itself differently than MC2 or is there something to be changed in the program?
