S7 - IE (TCP)

This mode allows the configuration of the connection via Industrial Ethernet (TCP).

Dev

Specifies the number of the device for ACCON-AGLink. The value can be between 1 and 512.

However, per driver a maximum number of 256 devices can be used. You have to use a second driver and the deviceOffset config entry for bigger numbers.

For a new connection the next valid value (the first entry in the data point _S7_Config where the IP address is not set) is calculated automatically and inserted into the field.

Connection type

Specifies the type of the connection for ACCON-AGLink. The following settings are available:

IP address

The IP address (or host name) of the CPU. To use a specific port, the port number can be stated with the IP address, e.g. "192.168.1.13:120". The default port for the S7 driver is 102.

Rack

The rack number of the CPU unit of the PLC. This has to be considered for different PLC assemblies, e.g. S7-300 and S7-400. Please note that WinCC OA stores the rack information as decimal values whereas Step7 and the SIMATIC manager use hexadecimal values.

Slot

The slot number of the CPU unit of the PLC. This has to be considered for different PLC assemblies, e.g. S7-300 and S7-400. Please note that WinCC OA stores the slot information as decimal values whereas Step7 and the SIMATIC manager use hexadecimal values.

Timeout [ms]

Defines the timespan for ACCON-AGLink in which all connections must be cleared. If the timespan is exceeded the following error message is displayed:

Asynch. ExitAdapter does not complete for <Verbindungsname> device <Geräteindex>

Active

This check box is used in order to set the connection to the peripheral device active or inactive. You can deactivate a connection that is already created and configured. The connection data point is not deleted and can be reactivated at any time. The status display changes from "Connected" to "Not Active"; if a connection is deactivated.

State

Shows the status of the connection to the periphery. The following states are possible:

  • "Not Connected" (Connection to the peripheral device lost e.g. PLC was disconnected from the network)

  • "Connected" (Connected with the peripheral device)

  • "General Query" (General query runs)

  • "Not Active" (Device with the associated check box set to inactive).

GQ

The General query button triggers a general query on the selected connection. The next received data will be sent to WinCC OA (without consideration of low level comparison and smoothing). See also the config entry AutoGQ on the page Possible config entries of the S7 driver). The driver executes an automatic general query when establishing a connection and at a redundancy switch.
