I have a 6GK5874-2aa00-2aa2 device, that I want to use for sending SMS messages about alarm states in the plant. I am using CPU 1512SP-1 PN (6ES7 512-1DK01-0AB0) There is an application example (https://support.industry.siemens.com/cs/document/54361177/sending-and-receiving-sms-messages-via-a-scalance-m-router?dti=0&lc=en-AU) that suits me for editing. I configured M874-2 via web server as described in the application example. Besides that, I have also configured it to send me SMS (in attachment) on the positive and negative edge of digital input just to test my settings of the mobile operator. The problem is connecting from PLC with M874-2, I have tried calling TCON function myself or using an application example, but the result is the same. I always get 80C5 error (the connection partner refuses to establish the connection, has terminated the connection or actively ended it). In application example port for communication is 26864, but when I use some net scan tool I do not see that that port is opened on my M874-2. |
