MicroLogix 1000 and PLC-500 A.I. Series Software Reference
16-14
Parameter Description
Message Retries Enter the number of times the processor should resend a
message to the master without getting an acknowledgment
and stopping. Valid range is 0-255.
EOT Suppression Generally at the end of a transmission the processor sends
an end of transmission (EOT) character. Toggle this
parameter to Yes to suppress the EOT character.
Parameters for DH-485 Master
Parameter Description
Baud Rate Communication speed in bits/second. Toggle baud rates
from 1200 to 19200.
Node Address Enter the address for the processor on the DH-485 network.
Valid range is 1-31 decimal.
Max Node Address Enter the highest station number on the DH-485 network.
Use this setting to speed communications by ignoring nodes
with higher addresses (the processor does not have to poll
beyond the highest address).
Token Hold Factor Enter a number from one to four to set the number of
transactions that the processor will make before giving up
the token. Setting this number higher increases processor
throughput, but decreases throughput to others on the
network.
