10.5 Digital I/OThe digital I/O module has 32 inputs and 32 outputs. Utilisation is as follows:4 * 4 inputs draw ratio 1 in BCD format. Provides the overall drawratio of 0.xxxx.16 inputs inputs for run, jog, enable and emergency stopsignals.The digital outputs are used to control display indication lamps, etc. on theoperator’s control panel.10.6 Analog I/OThe analog I/O module has 4 input and 4 outputs. Utilisation is as follows:• 1 input feedback from material thickness transducer• 1 input master line speed reference• 2 inputs material tension references for unwind and rewindsectionsThe analog outputs are scaled by the PLC to produce real unit readings onanalog meters.• 1 output material thickness, displayed in mm.• 1 output actual line speed, displayed in metres/minute.• 2 outputs material tension, displayed in Newtons.Profibus–DPIssue code: pbnu2 37
