XC43 Functional Safety
Will the XC43 (when paired with the MC43FS) inputs to be allowed for use in Functional Safety Marked Function Groups in a future version of IqanDesign?
Driving Low Dither Frequency Valves with XC4x Current Outputs
Has anyone had any success controlling valves that specify a low dither frequency below 71Hz with the XC4x current outputs?
We have a machine that is using a HAWE valve that specifies a dither frequency of 40-70Hz with 55Hz recommended. It also gives a range of dither amplitude of 20%-50%. The minimum frequency of the Cout channels on the XC4x modules is 71Hz. I'm sure 1Hz is not going to make a big difference if we set the frequency to 71Hz, but just wanted to see if anyone has had any similar experience or other recommendations. Just trying to avoid any possible stiction/hysteresis/chattering issues.
XC4x Firmware Updates
Say you have a brand new XC43. The firmware installed from factory is 1.0 (I think). How many times will the firmware update before reaching the current version of 1.03?
Also, the XC4x SIC module status lists a value of 140 as Firmware update. From the documentation that means the firmware update failed. Are there any other status values pertaining to the firmware?
What are the different values possible in the system info "InternalState" and is this channel accessible in the project?
XC44 HS+LS Overcurrent
We are experiencing a problem with the HS+LS outputs on an XC44 module connected to an MC43 as the master running IQAN 6.07. Pin C1:46 as the HS and pin C1:41 as the LS.
The outputs are being used to activate a solenoid. The circuit was wired to run through a relay latched by system estop, with a diode placed across the solenoid to protect the outputs as in the documentation.
This circuit is able to latch and unlatch the solenoid with no problems, and this was repeatable many times. However when the system estop is pressed for the first time and the relay unlatches and breaks the circuit there is no error. When the relay is energized and the circuit is connected again, when the output is turned on a message is displayed reporting that the LS pin is overloaded. This message then triggers on either side of the estop from that point on. Key cycle is able to "reset" to the first estop cycle. This behavior happened ~9/10 times the cycle was repeated. There were some occasions where the error did not trigger.
The overcurrent error will only trigger when the output is requested, the estop relay can be re-energized connecting the circuit and no overcurrent is reported.
Current measurements were taken on the HS+LS wire to investigate. The current on this wire never approaches or exceeds the listed 2.5A. This is the only load on that pin grouping, the other 3 LS pins were not used.
VIN voltage drops
Hello,
I have an odd issue, maybe power or ground reference related.
XC43 IQAN 6.08, sensors powered using the main 24VDC not regulated VREF.
When I start driving valves with the module the reported voltage from my VIN sensors drops by up to 5%.
It happens to all of them irrespective of the sensor type.
It also jumps around a ton.
This makes a huge difference on my 0-5800 0.5-4.5V sensors.
200+ PSI, not good for sensor accuracy.
Any ideas of what to try to fix?
Regards,
XC43 INPUT ERROR
I am working with a couple customers who are having "No Contact" Issues with XC43s installed to replace XA2s.
When looking at the XC43 module itself, the error code is 1:2 (one red, 2 yellows).
I'm assuming the module is getting an errant input somewhere which is causing it to shut itself down.
I would like to better understand this error code better. What causes an input error and under what circumstances does it cause the module to stop communicating with the master.
XC44 DOUT-(HS) SSP state (reverse feed)
Good morning, we have had a problem with an XC44 expansion module, when we connect more than 5 solenoid valves to the DOUT-(HS) outputs, during the initialisation process, the module is protected and goes into state: SSP (Safe Shutdown Path) with the blink code: R4:2 1:1:1.
The electrical installation has been checked several times and everything is OK and all the clamp diodes are installed properly.
If we start with the solenoids disconnected and when the initialisation process has passed we connect them, everything works correctly.
We have tried to replace the module and it didn't work either.
We have finally had to add several relays to control the solenoids so that the module starts correctly, but this solution involves a lot of tedious extra work.
XC4x C1 Harness
Hello,
This is a small but frustrating nitpick.
The XC4x C1 Prototyping Harness (Parker no. 20085116) comes with wires installed in the C1:4 and C1:20 position.
This is annoying, because in order to use these modules, you need to install the ID Tag. (Parker no. 20085131 for example)
So every time you use this (expensive) part, you need to de-pin these two wires, remove them from the harness, and install the ID Tag.
Ideally there would be no wires present in these slots.
Like the older style XA2 Prototyping Harness (Parker no. 5030030).

XC43 DOUT HS in parallel
When connecting loads to high side digital outputs in parallel, the manual says on page 96 "Increased drive capability
Power driver high-side is connected in parallel with adjacent output to drive double
load current." On page 116 it states the max load per output is 4 amps and max load per group is 6 amps. So when you connect in parallel is the max load 8 amps? Or 6 amps?
