Using an IO-module on an IoT2040 with NodeRed (v0.17.5) I’m trying to query its digital inputs. 24V are being applied for testing. I tried two different nodes for that. mraa-gpio-din (Intel gpios): It’s possible to read DI0 and DI2 successfully. However DI1, DI3 and DI4 are unresponsive. Also the status indicators (low/high) in the flow view are somewhat random and not accurate at all. In addition to that, a sporadic Uncaught Exception is occurring: “Uncaught Exception: TypeError: object is not a function”. Whenever this happens a NodeRed restart is required. iot2000-io-di (Simatic IoT2000): Using these nodes it’s possible to read all DIs successfully. However another sporadic error is occurring from time to time. Applying minor changes to the flow, then undoing them (in order to activate the Deploy button) and deploying the flow again fixes the error. At least until it occurs again. Those nodes require a trigger input. I’m using the supplied single pulse node here (tried both 100ms and 500ms). However while troubleshooting I replaced this single pulse node with a repeating Inject node. This seems to prevent said error from occurring. The smallest possible polling cycle of one second here is way too much for a productive usage. AttachmentIoT2040_errors.zip (328 Downloads) |

Hi, I know that the intel-gpios are not working as expected. Some DIs are working, some not. That's why we made the iot2000 IOs, but I am not aware of the described exepction. I will contact the developer of these nodes. There are some other DIs nodes for the IOT here. Maybe you can try them if they are working better. Best regards! |
Not working for IOT2050 support anymore from March 1st, 2024. |

Unfortunately now the error described here occures for us too. All queried DIs are "-1" occasionally. Afterwards no new values can be read until a restart |
