Hi, For example, %QB0 addresses the first output byte. Since this covers 8 bits, you will address 8 of the status LEDs of the corresponding outputs. However, the value you assign to the byte determines which LED turns on and which turns off. However, it may be easier for you to address a single output bit by using, for example, %Q0.0. Note that this is only a brief description of addresses in the PLC. You may need more basic information about PLC programming. You may find useful information at Siemens Automation Cooperates with Education (SCE). Kind regards |
