16.11.4 Communication Settings
Imagechecker communication settings
[4] Environment
41. Com. mode: Computer Link
42. RS232C
421. Baud rate (bps): set to the same as the PLC "Communication speed
setting"
The units for the communication transmission speed are in bits per
second. There are eight possible settings (1200, 2400, 4800, 9600,
19200, 38400, 57600 or 115200).
422. Length: set to the same as the PLC "Data length" setting
Set the number of bits used to represent one character of data. Select
either 7 bits or 8 bits.
423. Stop Bit: set to the same as the PLC "Stop bits" setting
Set the number of bits for the signal that identifies the end of the data.
Select either 1 bit or 2 bits.
424. Parity: set to the same as the PLC "Parity check" setting
Set type of parity check for the appended parity bit that is used to check
that transmission was correct. Select either None, Even, or Odd.
425. Flow Control
Set the handshake flow control method. Select either None or Xon/Xoff.
43. Serial Output
431. Type No Register
Specify a data register number (in the range 0 to 9999) for performing
the PLC product switch request.
432. Top Data Register
Specify a start data register number (in the range 0 to 9999) for when
data is output to the PLC.
433. Timeout
Set the timeout for the response after output of data to the PLC and the
response to a product type switch number request.
434. Output
Specify the number of bits for the output data.
Select either 16 or 32 bits for the number of bits.
16 bits: values in the range –2
32 bits: values in the range –2
16 − 60
