The V addresses of the LOGO are addressed via DB1 within PLC-Lab. This address can be specified in the configuration dialog of the NAI. The analog network input has the address VW0. When you now drop the block of the analog network input over the AI1 (release the left mouse button), the block of the AI1 is replaced.

To do this, select an analog network input from the catalog of the LOGO programming software and drag it into the drawing board of the circuit over the analog input you want to replace. Its function is to be simulated with the help of PLC-Lab.įirst, you have to replace the analog input AI1 with an analog network input. The analog input AI1 is used in a circuit. For example, to address the analog network input with the address VW0 in PLC-Lab, enter DB1.DBW0 as operand.Įxample for the simulation of an analog input: This V area is addressed in PLC-Lab via DB1. their address starts at VW 0 and is 16 bits wide. These are located in the LOGO in the V range, i.e. For this reason, analog network inputs must be used for the simulation.
via a slider object in PLC-Lab, has no effect on the analog input in LOGO. V area LOGOĪnalog inputs of the LOGO controller can only be read. The following table shows the relationship between V operands and the DB1 in PLC-Lab. These V operands are addressed in PLC-Lab via DB1. The network inputs are connected to bit addresses of the V range in the LOGO. A later simulation of the program is possible at any time. This means that the circuit program can be used unchanged in the real system after the simulation. The preferred procedure is to connect the input and the network input to an OR block and to continue using the output of the OR block. This corresponds to the address V0.0 to which the network input NI1 is set.īecause digital inputs of a LOGO cannot be overwritten directly, their function must be taken over by network inputs. The push-button in PLC-Lab is set to the operand "DB1.DBX0.0". You can always use simulations with any later modifications. After the simulation, the circuit can be used unchanged on the real system. The network input is then influenced by the virtual PLC-Lab system. This has the advantage that the signal of the push-button can come on the one hand via the input of the LOGO and on the other hand via the network input NI1. The network input is set to address V0.0. In the first step, input I1 is routed to an OR block a network input NI is inserted and also connected to the OR block. This push-button is to be simulated via PLC-Lab. In a system, a push-button is connected to input I1 of LOGO. For example, to address the network input with the address V0.0 in PLC-Lab, enter DB1.DBX0.0 as operand.Įxample for the simulation of a digital input: This V area is addressed in PLC-Lab via DB1 (data block 1). In LOGO, these are located in the V area, i.e. For this reason, network inputs must be used for simulation. via a push-button in PLC-Lab, has no effect on the input in the LOGO. Inputs of the LOGO controller can only be read. This is possible with the LOGO controllers 0BA7, 0BA8, or newer.īefore a brief example shows the interaction between PLC-Lab and a LOGO, we will now look at the simulation and addressing of the different operand ranges of a Siemens LOGO. PLC-Lab can be connected via Ethernet to a Siemens LOGO.
