Communications Functions Section 1-9
Note If an out-of-range value is set, the following communications conditions will
result. In that case, reset the value so that it is within the permissible range.
Communications mode: Host Link
Communications format: Standard settings
(1 start bit, 7-bit data; even parity, 2 stop bits,
9,600 bps)
Transmission delay: No
Node number: 00
1-9-13 Transmission Data Configuration
When no-protocol communications are used, TXD(48) is used to send data
and RXD(47) to receive data. The maximum amount of data that can be either
sent or received is 259 bytes, including the start/end code.
• No Start or End Code:
• Only a Start Code:
• Only an End Code:
• Both an Start and End Code:
• End Code of CR, LF:
• Start Code 00-FF/End Code CR,LF:
Note 1. The start and end codes are set in DM 6648 to DM 6649 and DM 6653 to
DM 6654 of the PC Setup.
DM 6648 00 to 07 Node number (Host link, effective when bits 12 to 15 of DM 6645 are set to 0.)
