4.3 Configuration Example for MELSEC System Q
For this example, a MODBUS/TCP slave consisting of the following STlite modules is used:
– Head station STL-BT1
– Power supply module STL-BPS (with bus power supply)
– Digital input module STL-DI8-V1 (8 inputs)
– Digital output module STL-DO4 (4 outputs)
– Analog output module STL-DA4-V1 (4 channels, 0 to 10 V)
– Analog input module STL-AD2-V (2 channels, 0 to 10 V)
–End module STL-ET
4.3.1 Settings for the Master Station
Start GX Works2. In the project navigator window, select Intelligent Function module. Right click

NOTE
For the specifications of the modules and the installation procedures please refer to the installa-

STlite modules with power contacts (male contacts) cannot be linked to bus modules with fewer
power contacts. In this case install a power supply module between the two relevant modules.
