Connection

This chapter explains the configuration of connection parameters for the driver.

This tab allows you to configure general connection parameters, such as IP address and access point. Depending on the configuration, you may have to define these parameters for a redundant connection (connection 2) too.

Figure 1. Connection tab

First device

IP address

Define the IP address of the connection(s) to the device.

Access point

Define the appropriate access point. All access points from the PG/PC interface settings are available, e.g.:

  • CP_L2_1
  • MPI
  • S7ONLINE
Note: When using multiple network interfaces, it is sufficient to use S7ONLINE as access point. No additional access point must be created.

Station

This spin button is only displayed if the defined PLC type is S7-1500 Soft PLC. It allows you to specify the station number.

Note: When connecting to a SIMATIC ET 200SP Open Controller with RJ45 interfaces X1 and X2, proceed as follows: The station number must be 0 for X1 and must correspond to the slot number configured in the TIA portal for X2.

CPU 1 / CPU 2

If the PLC type S7-1500 R/H Single is used, the settings for the system's CPUs are stated here instead of the IPs of the connections.

These settings represent the configured order of the physical CPU devices forming the S7-1500 R/H system.

This configuration step is called "Redundancy ID" within the TIA Portal and must be done during setup/pairing of the R/H system.

Validating the configuration order of CPU 1/CPU 2

In case the the correct CPU order is unknown or cannot be changed, proceed as followed :

  1. Define the order of IP addresses arbitrarily.
  2. Set one of the CPUs to STOP state and validate within the tab "State details" if the state of the CPU is correctly displayed.
  3. If the displayed state is correct, no further changes are required, otherwise the order of the configuration for CPU 1 and CPU 2 must be swapped.
