    Starter kit for ecomatController EC2121 The ecomatController devices contain two independent programmable logic controllers:  StandardPLC (CR711S standard)  SafetyPLC (CR711S SIL2) For this first introduction, only the StandardPLC is used. The distribution of the resources (e.g. memory) to the two controllers does not have to be taken into account here.

    Starter kit for ecomatController EC2121 > Create the program 57283 In the first small program a two-hand control is to be implemented which is used for presses, for example. There are two pushbuttons on the press which are installed so that they cannot be operated with one hand.
  • Page 31 Starter kit for ecomatController EC2121 5.3.3 Structured programming 57286 In principle, the complete program can be contained in only one block such as the PLC_PRG. This becomes quite confusing, however, and the fault location is difficult. It is better to distribute different program sections to different blocks. Then the blocks are activated one after the other in PLC_PRG.
