The PS416-COM-200 card provides serial, asynchronous point-to-point communication with various data terminals. Data terminals can include:

• PCs, host computers
• Modem
• Automation equipment
• Data acquisition systems (bar code readers, sensor systems, meters )
• Robots

Features

• Space required: 1 slot
• Up to 8 cards can be inserted in the basic unit; note the total current required
• Communication: half/full duplex (with RS 485 interface only half duplex)
• 1 interface per card
• The interface can be adapted with 5 different interface modules
• RS 232 C with control cables
• RS 232 C without control cables
• 20 mA (TTY) passive
• RS485
• RS422
• Even/odd/no parity
• Character format: 7/8-bit with 1/2 stop bits as well as 1 start bit
• Preselection of baud rate from 300 bit/s to 19.5 Kbit/s through the software
• Communication secured with data flow control through hardware and software handshake
• The entire communication with PS416-COM-200 is handled by the COM function block in Sucosoft S40

Engineering

• The card is configured with the Sucosoft S40 Topology Configurator
• Modes:
  - Transparent mode 1
  - Transparent mode 2
  

Transparent mode 1

• Transparent (interpretation-free) data transfer of fixed-length data bytes
• The lengths of send and receive data can be specified separately using the COM function block in the PLC user program. The data length can vary between 1 and 256 bytes.

Transparent mode 2

• Transparent (interpretation-free) data transfer of data bytes with variable length between 1 and 256 bytes
• Data transfer with specified start and stop characters
