SLC Communication Channels 13-51
Table 13.15 Define these communication parameters when configuring a SLC 5/03, 5/04, or 5/05 processor for DF1 full-duplex
communication.
Tab Parameter Default Selections
General Diagnostic File 0 SLC 5/03 (OS 302, Series C or higher), SLC 5/04 (OS 401, Series C or
higher) and SLC 5/05 only. Select an unused file (9 to 255) to store
channel status information. You must define a diagnostic file in order
to be able to view channel 0 status. See Table 13.25 on page 13-82
for a file description.
Channel 0
System
Baud Rate 19,200 Select a communication rate that all devices in your system support.
Configure all devices in the system for the same communication rate.
Parity None Parity provides additional message packet error detection. To
implement even parity checking, choose Even. To implement no parity
checking, choose None.
Stop Bits 1 Match the number of stop bits to the devices with which you are
communicating.
Source ID 9 This is the address, in decimal, that is used as the source address in
any message initiated by this processor. When DF1 passthru is
enabled (S:34/5 is set), configure the source ID to equal the channel
1 DH+ address in an SLC 5/04, or zero in an SLC 5/05 processor.
Control Line No Handshaking This parameter defines the mode in which the driver operates.
Choose a method appropriate for your system’s configuration.
• If you are not using a modem, choose NO HANDSHAKING.
• If you are using full-duplex modems, choose FULL-DUPLEX
MODEM.
See page 13-86 for descriptions of the control line operation settings
