This satellite is intended for automation applications that require local displaying of magnitudes (e.g. motor speed, production count, workpiece length). The serial port is intended for interfacing to an operator terminal or PC or other controlling or monitoring machinery and the bit inputs and outputs for interrupt generation, event counting/timing, state monitoring and control.
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.
Local serial communications port. Supports the protocols: RS232 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.
Large 4 digit LED display. The display is bright and visible from far and wide.
Four 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. The outputs can be configured as optocoupled NPN transistor or 5 VDC types.
Eight galvanically isolated bit inputs, of which four drive the processor directly and its interrupts. All inputs enable fast data capturing as well as control of local automation (such as workpiece counting, position/speed from encoder pulsing, scrap rejection) and as already mentioned, the operator is 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.
