CP474.60-1 can't go to online mode

After transfer new OS 2.51 (switch in position 0) can’t go to online mode to transfer project (switch in position 1) I’m using AS 2.7.0. COM1, 115200, none - nullmodem (I used other speeds without result - tools-> option → Online → Online configuration). I’m trying configure Acopos 8V1022.00-1 and only AS2 support this CPU and Acopos.

look at this @Pawel_Zwolak …hehe

but for 8VI1022-1 is different story, we need CAN interface and old motion library no more supported on AS 3 and 4

What do you see for status indicators?

If you manually change the operating mode to “Boot” can you connect to the system?

ERR and RDY → lit. RS232 → flickering one per sec. If I change to “0” I can transfer OS to PLC, but after succesfull transfer can’t connect in “0”, “1”, “F”.

Hello Pawel,

you must activate INA communication. Then please transfer the operating system again in switch position 0.

Force INA is checked, after transfer OS and change to 1 position - I still see:

Please check the serial interface settings in the project and adjust the online connection settings accordingly.
