Hello, i have problem with 3 PLC's. After Power off - power on on PLC they goes to STOP/ERROR. I think problem is with RS485. PLC firmware is 2.0 RS485 firmware 1.0 I have loaded v1.0 modbus rtu (master) and v1.0 (load) If i i'm trying in MAIN OB call all blocks at once, then after power of-power on i get STOP/ERROR So i try to call all FC then -|/|- first cycle. Load and master i call after 30s after -|/|- first cycle. So after that i get STOP/ERROR not every time, but sometimes. After that error i reset to factory and then upload program again. But problem is not solved. Maybe somebody has any idea? p.s PLC 1214C DC/DC/DC firmware 2.0 AttachmentDiagnostics.pdf (720 Downloads) |

Hi, is you hardware correct configured and have you download them? The Load block you only need to call in Startup-OB to configure your RS485 modul. Did you parameterzied correct HW-ID of RS485 modul at load block? Also only use blocks with version 2.0 together if you have Firmware 2.x. Do not mix 1.0 and 2.0. Please install also TIA v11 update 2 (http://support.automation.siemens.com/WW/view/en/52258326) and take latest firmware 2.1.2 (http://support.automation.siemens.com/WW/view/en/38693794) |
