I/O Memory Allocations
Section 2-3
Note
1.
The default settings used for Host Link, protocol macro, and loopback test
modes areas follows: Baud rate: 9,600 bps, start bits: 1 bit, data length: 7
bits, parity: even, and stop bits: 2 bits.
The default settings used for Modbus-RTU slave mode are as follows:
Baud rate: 19,200 bps, data length: 8 bits, parity: even, and stop bits: 1 bits.
2.
A System Setup error will occur if 1, 3, 4, or 7 to E is set, and the Unit will
operate with the default Host Link settings (9,600 bps, unit number 00).
3.
The PTs connected to the port must also be set for a 1:N NT Link. Com-
munications will not be possible if a PT is set for a 1:1 NT Link.
4.
Do not set B to F settings, and baud rates that are not supported by the
serial communications mode. A System Setup error will result. Settings of
1 and 2 are reserved for the system and should not be used.
5.
With CTS control, turn ON the request to send (RTS) signal before stating
to send, and be sure the clear to send (CTS) signal is ON before sending
data. When there is no CTS control, turn ON the request to send (RTS) sig-
nal before sending, and then send data without checking the request to
send (RTS) signal.
6.
For settings below 00C8, use 00C8 Hex; for settings above 03E8, use
03E8 Hex.
