Programming manual SCU-series 2.6. General safety information NOTICE: Work may only be carried out after the SCU installation manual and the SafePLC2 programming manual have both been read thoroughly- DANGER Programming or changing the programming can cause malfunctions. Malfunctions can cause unexpected starts of the complete system.
Page 18: Requirements
Programming manual SCU-series 3. Requirements 3.1. SCU unit The SCU is a Master unit for FSoE communication to read encoder data and switching statuses of external Slave units to implement safety functions. The SCU can send, receive and process safe data via FSoE and unsafe data via EtherCAT. In the EtherCAT network, the SCU only functions as Slave.

Page 20: Fsoe And Ethercat
Programming manual SCU-series 3.2.3. FSoE and EtherCAT The Ethernet frame of the EtherCAT network can contain non-safe as well as safe data. The safe data are called FSoE data, and are assigned to the FSoE Master-and-Slave protocol stack. These data are transferred cyclically, and are thus included in the PDO of the respective participant. The SCU is designed as FSoE Master, and it starts the safe data transfer via FSoE.

Programming manual SCU-series 4.4. Process The program SafePLC is a graphics-oriented software to create an SPC-based monitoring program for an SCU system. With the device, it is possible to closely monitor drive motors. The process described below, has proven most successful for SCU-devices, but it is not compulsory. General information: The program requires the write permission and the read permission of the user registered on the PC used for programming.
Page 68 Programming manual SCU-series To create an application, proceed as follows: 1. Select the device type to be programmed: After SafePLC has been started or after a new logic diagram has been created, an empty work surface appears. All available devices are in the library. By clicking on the appropriate module, inter alia, the description window shows the following files: programming interface, digital I/O, outputs, inputs etc.
Page 69 Programming manual SCU-series NOTICE: Due to the ressources involved, and because of their adminsitration in the programme environment, is not recommendable to change the type of equipment later on. The following Properties window can be used for every input cluster to assign a name and to select the parameter “Cycle time”.

Programming manual SCU-series 4.6.6. The logic modules These modules are the basis for the creation of a program for the safety application. They enable the logical connection of the inputs with monitoring functions to the outputs. Only in the “Funktionsplan” [Function Chart] view, it is possible to insert logic modules. Otherwise, the corresponding module commands are disabled.
Page 93 Programming manual SCU-series The programme automatically creates a new connection in the terminal scheme and in the circuit diagram. The program draws the connection by inserting additional control points (break points) on the basis of a bisection algorithm. The graphical representation can be adjusted and the general representation can be optimised by moving the function blocks (if automatic arrangemetn has been deenabled).
