Library 'biaCYL_lib' for B&R platforms
The ‘biaCYL_lib’ library contains functions and function blocks that can be used
for the control of
pneumatic and hydraulic valves and cylinders.
Function block ‘CYL_DiscreteCylinder’
Contains functionality for operating a valve and/or cylinder (via a discrete valve).
This functionality includes:
- support of 5/2 monostable and bistable valves, and 5/3 valves
- support of position detection on ‘work’ and/or ‘return’ position
- support of a simulated travel-time when no position detection used
- monitoring of status and performance (traveltime, raising of alarms and warnings
on several criteria )
- inhibit-functionality (inhibiting of movements)
- support of manual operation (via HMI or SCADA system)
- interface built with 'enumerate' type variables (easy application debugging)
Configurable are:
- valve-type and end-effector detection type
- device ID (numerical and in text)
- endstate definitions (in text, e.g. 'up', 'reject' etc. for HMI and
SCADA)
- default- and maximum allowable traveltimes
- error-, warning- display-offsets (for HMI purposes)
Monitoring of operation:
- monitoring and guarding of traveltimes
- monitoring and guarding of end effector performance and failures
- guarding of inhibit-inputs (inhibiting of movements)
- guarding of invalid commands or configurations
