Connect OP77B to TI555-1106 (CP5434-DP annex card)

Parameters to be set

To edit the parameters, double-click "Communication > Connections" in the project window of the HMI device. "SIMATIC 500/505 DP" is selected in the "Communication drivers" column in the work area. Change the protocol parameters of the connection in the Properties window.

Device-dependent parameters

• Interface

  Under "Interface" you select the interface on the HMI device over which the connection to the SIMATIC 500/505 will be established. The type is set automatically depending on the selected interface set under "Interface".

  For further information, refer to the relevant device manuals.

• Baud rate

  Under "Baud rate" you select the transmission rate at which the HMI device communicates with the SIMATIC 500/505 in the network configuration. The same baud rate must be set on all devices in the network.
  System default: 1500Kbps.

  Note The highest station address must be less than or equal to 63 if you set a transmission rate of 1.5 Mbaud at OP 73 or OP 77A. If connecting a TP 170A to a SIMATIC S7 station at a transmision rate of 1.5 MBaud on PROFIBUS DP, set a value less than or equal to 63 for the highest station address (HSA).

  
  

PLC-dependent parameters

• HMI address

  Under "HMI address" set the PROFIBUSDP address of the HMI device.

  Values from 3 through 125 are permitted.

• Block length

  Under "Block length" you specify the assignment of the I/O area used for communication between the HMI device and PLC. The size of the I/O area influences performance.

  The configuration is implemented according to class B (basic DP slave complying with EN 50170). You can select four different configurations:

  • - Class B tiny
  • - Class B small
  • - Class B middle
  • - Class B big

  The assignment of the I/O areas is fixed with the four various settings. The following table shows the assignment of the I/O areas:

The settings in WinCCflexible must match the configuration data of the interface module, for example CP5434 DP.
