Basic functions of fast inputs/outputs
The I/O compound modules described below belong to the I/O system 1000. The
system is suitable for the implementation of complex automation applications and
consists of a bus coupler module and several I/O compound modules. The in-station
communication of these modules as well as the exchange of process data, parameter
data and diagnostic information takes place via an internal backplane bus.
2 digital inputs with time stamp function - EPM−S207
This "fast input" detects up to two binary control signals from the process level and
transmits these signals to the higher-level bus system. An internal 16-bit counter
(µs−ticker) can be used to record the occurrence time (latch value) of a certain event
(time stamp functionality).
Fast inputs are used for:
• Alignment of discontinuous motion to a registration mark
Flying saw / rotary knife / feed
• Alignment of continuous motion to a registration mark
Rotary processing (stamping, embossing, printing)
• Measurement of workpieces
• Position latch on virtual or real axes
Features:
• 2 digital inputs
• Up to 15 time stamp entries can be recorded
• Suitable for switches and proximity switches
2 digital outputs with time stamp function - EPM−S310
This "fast output" detects up to two binary control signals from the higher-level bus
system and transmits these signals to the process level using the time stamp
functionality. Here the setting of a certain output is based on the internal 16-bit
counter (µs-ticker).
Fast outputs are used for:
• Cam groups whose outputs need to be set very precisely depending on the
position.
Features:
• 2 digital outputs
• FIFO buffer for up to 15 time stamp entries
• Control via process image
Note: Both I/O compound modules are provided with own 16-bit counters (µs-
ticker) which must be synchronised by the RWB controller.
