Most modern machinery have a serial channel for communicating with other machines and
this satellite is intended for all these. Its multiprotocol capability allows
it to interface with most (if not all) PLCs, weighing units, small terminals, NC tools, measuring instruments etc. having a serial port.
This satellite platform features:
RS485 Quamatic Net serial port. The net line is galvanically isolated from the other resources on the platform, while the serial data are available locally per RS232 with no flow control (RX and TX only) for debugging and diagnostic purposes.
Multiprotocol serial port. Supports the following protocols: RS232, RS422, RS485 and Optocoupled TTY (20 mA). The port employs a 16x50 IC whose operation is completely programmable and configurable.
8xC51Fx processor, 32K SRAM and 64K EPROM. Given the parametric nature of the Quamatic line, operation is not limited by the processor type or the available memory.
Watchdog/Sanity timer. Its operation is transparent to the user.
Two galvanically isolated bit outputs. These can drive local automation (such as relays, contactors, alarms, vanes) supporting the operator via the running application on a local PC (connected to the satellite serial port) in the productive running of the equipment.
Two galvanically isolated bit inputs. These inputs activate processor interrupts and as such enable fast data capturing as well as control of local automation (such as workpiece counting, position/speed from encoder pulsing, scrap rejection). As already mentioned, the operator can be supported effectively in running the equipment productively. The bit inputs interface to all types of signaling (normally open/closed contacts, current source/sink and so on) and can be digitally filtered or debounced via the Configuration File.
