MIO Module not working

[cerberus78]

Hello

I have connected a DIO and MIO with my rev pi connect 4.

The MIO module is not detected and blinks in red (on switch on the Power led is green then all leds blinks red (Power, Out and IN)

I have checked the input which is 24V and DIO module is working perfectly.

piTest -d gives

Can you help me please ?

Hello cerberus78,
check the mechanical connection of the PiBridge adapter on the MIO module.
Then restart PiControl with

Code: Select all

piTest -x

Does the PWR LED light up green afterward?

If not, check whether a firmware update is possible:

If all else fails, please send me an SOS report:

at the first boot the power led is green then blinks red
with piTest -x, it keeps blinking in red.

Hello

Hello, I have followed all recommendations and did not manage to boot it/detect it

Hi cerberus78, thanks for the information and your patience here. I can see that you are using a DIO, MIO and a Connect 4 module.

There are always problems when initializing the PiBridge, which can be seen here in the "kern.log":

Code: Select all

Jul 16 10:33:01 RevPi107353 kernel: [ 1147.327615] pi-bridge serial1-0: receive head error in io-req
Jul 16 10:33:01 RevPi107353 kernel: [ 1147.327630] piControl: DIO addr 32: communication failed (req:6,ret:-5)

I have the following ideas:

• Swap the positions of the two modules and the PiCtory configuration accordingly (don't forget to save and reset the driver)
• What happens if you then restart PiControl with "piTest -x"? Are all PWR LEDs then constantly green? If no, then continue:
• Only operate a single module. Then try to update each of them:
• So MIO + RevPi Connect, adjust PiCtory configuration, save and driver reset, then "piTest -x"
• Then DIO + RevPi Connect, adjust PiCtory configuration, save and driver reset, then "piTest -x"
• Again - what happens if you then restart PiControl with "piTest -x"? Are all PWR LEDs then constantly green? If no, then we need to talk about an RMA.

==> Already tried before posting, nothing changes

==> we can see some green but disapear quickly

==> At boot, the power is green but after few seconds it turns to red
I have tried lot of bridges but nothing changes..

Hello cerberus78, I have used the PiCtory configuration from your SOS-Report and created a test setup here:

PiCtory Configuration

Test Setup

So I get no errors even after 15 minutes. The Kern.log also looks unremarkable.

Hello cerberus78, I assume that one or more of your modules are defective. Please follow the steps in the "Defective Device Checklist" so that we can help you.
