HIL Simulation using SPI Digital POTS

2019-03-07T15:10:50Z

Hi Mike,
you can use example 0501-01 (generic serial communication) or any of the 0401-xx examples on Modbus RTU communication. The USB RS485 adapter will appear as e.g. /dev/ttyUSB0, which you will use as the identifier of the serial bus.

I have the best experience with FTDI-based USB adapters. With other brands I sometimes had problems changing the baudrate.

Kind regards,
Jaroslav

RexDuino (USB) over ethernet

2019-01-28T15:20:25Z

Hello,

I was wondering is it possible to connect Arduino boards over ethernet and use them as RexDuino modules?

Either using Arduino board with ethernet port, or maybe other device as ethernet to serial bridge? (for this purpose maybe NanoPi? really cheap).

Did anybody tried something like this?

Regards
Hubert

btw - maybe someone have some experience with using cat5e ethernet cable as USB to USB connection (direct, no amplifiers etc)?
I was trying to establish such connection (R PI - Arduino Uno) over cat5e cable - around 35 meters distance - without success. But I'll give it another shot, maybe USB connectors wasn't properly mounted smile

Hi Tom,
it's working in the new version, which is being tested. I'll get back to you via e-mail.

PWM on Monarco Hat

2019-01-15T03:48:59Z

Hi All,

I need to PWM a MOC3023 optocoupler from the Monarco Hat. I'm not 100% sure on how to do this as the MOC3023 requires 3v3 and the digital outputs are 5-40V. Whats the best way the achieve this? The MOC3023 needs to be driven by 5mA.

Cheers

Rexduino counter problem

2018-12-17T10:09:17Z

Hi Bodie,
this will need a thorough analysis, at the moment I do not see any potential cause of the problem. Can you please try running your algorithm on a Raspberry Pi 3 and check if the problem persists?

Best regards,

Recovering SD card on Monarco HAT

2018-12-03T18:07:17Z

Hello Selam,

sorry to hear that you have difficulties with SD card. The process of making your Raspberry Pi up and running again would be following:

1) Perform step by step installation according to the Chapter 3 in Getting Started Guide: https://www.rexygen.com/doc/PDF/ENGLISH … df#page=10
2) Once REXYGEN installation on Raspberry Pi is successfully finished, you need to reactivate your license. Please, make an account at https://licensing.rexygen.com and I will pair the licence you bought with this account. Afterwards you will be able to reactivate the licence for your Raspberry with new SD card.

Monarco HAT firmware will remain untouched - no need to flash it again.

Just let me know when your REXYGEN account is ready and send me (support(at)monarco.io) the e-mail address which you used for the account.

PS: More about licensing can be found: http://support.rexygen.com/knowledge_ba … -mechanism

Error when creating bootable image for WAGO PFC200 (750-8202)

2018-11-23T18:46:58Z

Thanks Jaroslav,

All working now.

RTFM i guess.
The error when copying the image threw me off and it mistakenly assumed that there was a problem.

Monarco HAT Digital Output Signal Inverted?

2018-11-20T23:44:52Z

Hi,
sorry to hear you are struggling with the DOs. All your observations are perfectly valid and you did pretty well. Here is the explanation of Monarco HAT digital outputs in detail.

Either change your wiring or use the NOT block between the timer and the output. Note that the latter might not work if 5V is not high enough for the receiving device.

Hope this helps, let me know.

Kind regards,
Jaroslav

Modbus Registers

2018-11-14T08:50:14Z

Hi Mike,

"Slave X not responding" means that the communication with slave wasn't successfully created. The reasons can be:
- wrong communication parameters (baudrate, parity, ...)
- wrong wiring
- wrong Slave ID (slave address)
...

Do you have any working example with the controller using a 3rd party software for modbus communication? Just to be sure that the parameters are correct.

Cheers, Tomas

Master/Slave RPi 3 and RPi Zero

2018-11-12T07:45:16Z

Hi JL,
this is feasible, RPi Zero can run RexCore just like any other Raspberry Pi model, you just need to add a USB wifi dongle (or use Zero W). USB adapter for wired Ethernet is also an option. I'm supposing you are considering Modbus TCP on a local network. See example 0402-01, which is included in REXYGEN Studio.

Please let me know if the master station will run RexCore as well. If so, there are other possibilities to exchange data, e.g. REST API. See example 0302-01 for this approach.

Let me know if you have additional questions.

Kind regards,
Jaroslav
