The measuring range can be set as desired per channel or per channel group. The resolution is 16 bits including sign. An analog value (a channel) occupies 16 bits, in other words two bytes. 3). One status LED per channel indicates whether the channel is deactivated, working properly, or an error has occurred. The input channels are not isolated from each other. There is galvanic isolation between the channels and the backplane bus and between the channels and the internal power supply. Fig. 4 Analog output modules The CPU can use analog output modules to continuously provide actuators with analog setpoints.
The num- 47 2 SIMATIC S7-1500 automation system ber of modules a power segment encompasses depends on the electrical power that is provided and consumed. An additional load current supply is needed for supplying the sensors and actuators (Fig. 2). Central configuration of an S7-1500 station Configuration without system power supply, one power segment CPU Modules The CPU is supplied with 24 V DC, and the CPU in turn supplies the other modules via the backplane bus. S ... ESC OK Configuration with system power supply, one power segment PS CPU Modules A system power supply (PS) supplies the CPU and the remaining modules with power via the backplane bus.
