4 Installation
The SIRIUS monitoring relay (4) is connected to a digital input of the LOGO! logic
module. A three-pole wire electrode (8) is connected to the SIRIUS monitoring
relay.
In this set-up plan, the pressure measuring transducer (The SITRANS P pressure
measuring transducer must be removes!) is replaced by a S7-1200, DC/DC/DC
(1), which simulates the controlled system. The functionalities of the simulation are
described in chapter 3.5.
For the simulation, analog signals are exchanged via Ethernet. For this purpose, a
Compact Switch Module CSM 1277 (11) with 4 RJ45 ports is needed.
Via ETHERNET cable, the LOGO! (2), the port X1P1 of the S7-1200 PLC (7) and a
standard OC (10) are connected to ports of the Compact Switch Modules.
* optional components; simulation possible even without these components
