Hardware structure
The following hardware components are used in the serial module:
•
Serial controller (UART, two-channel)
•
RS232 driver for RxD, TxD, CTS, RTS for each channel
•
RS422 driver for RD+, RD-, TD+, TD- for each channel
•
RS485 driver for RxTx+, RxTx- for each channel
•
Three 16-bit hardware counters as protocol time base.
•
High-speed optocouplers for electrical isolation of the communication signals
•
Discrete DC/DC converter with two electrically isolated output voltages for the
communication channels
•
Optocouplers for monitoring the electrically isolated voltages and, thus, possibility
of alarm signaling in case of failure
•
EEPROM for configuration data and error memory
•
Isolator allowing you to plug the module in or remove it while the AC 800F is
running.
•
26-pin high-density Sub-D socket with the signals of the two channels
In order to ensure electromagnetic compatibility, the communication signals of the
serial channels are applied to the Sub-D socket via SMD-EMC filters.
Data is transferred between the AC 800F and the serial fieldbus module via an 8-bit
data bus. The transmit and receive data is exchanged with the CPU through interrupt
control.
