 ====== Controlling a PLC through SSCP protocol from another PLC  ======
-The SSCP protocol (Shark Slave Communication Protocol) is a proprietary communication protocol of Mervis systems. When compared to Modbus, SSCP holds the advantage of higher data transmission speed and support of secured communication. It serves for configuration, programming or data transfers. Data transfers are then the main focus of this tutorial - specifically, it demonstrates how to set up two PLC to allow one controller to control the other.

 ====== Connecting multiple Unipi PLC’s through the SSCP protocol ======
 Do you need to use one Unipi PLC to read from or write to I/O’s of an another Unipi PLC? The SSCP communication protocol will allow you to do exactly that. In more complex projects the SSCP can be also used to relay variable values or data from various sensors. This tutorial will show you how to set up the SSCP.

   * PLC_Master can send the variable into PLC_Slave each second – however, this will result in clogging up the communication and slow response of the project. This solution was used for this tutorial simply because the logic in PLC_Slave is in this case irrelevant.
