Hi, I have problem with Modbus Server CP S7 400, by CFC.

I have the status error A0FF, I have a CP443 in the datasheet support AG_CONTROL.

I dont know, What is my wrong in the configuration of the block and the CHART.

the conection is ONE SIDE.

my IP PLC CP is 192.168.0.10

the Hardware NET PRO is right.

1

1FFE.

port 502

I try to connect by MODBUS SCAN software to the PLC, Dont have conection and try with the Wincc driver MIODBUS Premiun Micro, the answers It is Same dont have conection to the server.

In my chart have counter to error and done ever is counting the error, never done.

Please is anyone have a configuration of SERVER Modbus TCP.

Split from 400h modbus tcp ip communication problem.

Hi RenatoAlex

When you try to communicate with the simulator, have you checked the connection in NetPro? Is it connected or does it wait for a connection?

A0FF means that connection is currently not ready for communication and that you should check the connections. If applicable correct the value at check_conn_cycle. The error can also occur when a CP is used that does not support AG_CNTRL.

Yes I check but the conection is passive in red wait conection, never connect.

I change the time_cycle. And the CP It can support AG_Control, I dont know is because I work only with One CPU S7 400 H, I dont have 2 for the redundancy and when I created the project create like a normal S7400, Anybody have any example of Server Modbus TCP configuration, please shared me.

In the manual more details is for Client Modbus.

Another comment is, I have to implement in a PCS7 V6.1.

Firts I am trying the configuration in the PCS7 8.1 Sp1.  Today i can start but is a random the start, I dont know how it is the start of the communication of my block Server Modbus TCP S7 400.

I dont know if I need to do something in the OB100, I am programming in CHARTS, any advices about this configuration ?.
