B-52 SLC Status File
S:34/5 Dynamic Config DF1 Passthru Enabled Bit
If channel 0 is enabled with a DF1 protocol and this bit is
SET, then the passthru operation is enabled between
Channel 0 and Channel 1. Passthru supported DF1 protocols
include DF1 Full-duplex, DF1 Half-duplex, and DF1 Radio
Modem. Refer to Chapter 14 for additional passthru
information.
•••
S:34/6 Dynamic Config DF1 Remote/Local Passthru bit
When set, SLC 5/03 DF1 passthru command packets are
transmitted on the channel 1 DH-485 network as local
command packets. This is important to set when trying to
access nodes on a DH-485 network that do not support
remote packets. When reset, the SLC 5/03 DF1 passthru
command packets are transmitted on the DH-485 network
as remote command packets. The default is reset.
•
S:34/7 Status Local Passthru Queue Full bit
This bit is set by the SLC 5/03 processor when there are no
available entries in the passthru queue. Entries may be lost
if active nodes on the Channel 1 DH-485 network fail to
respond. Use this bit in conjunction with the ACL
instructions to flush the passthru queue. Refer to chapter 10
for more information regarding the ACL instruction.
•
S:34/8 Status Processor Secured Bit
This bit indicates that the processor has been secured
through RSLogix 500 version 7.10 or higher. Once you have
been authenticated and authorized via RSAssetSecurity, you
will be able to go online and upload and download this
processor using RSLogix 500 version 7.10 or higher. If the
processor is secured, the only way to unsecure it is to either
disconnect the battery and clear processor memory back to
factory default, or install a memory module with an
unsecured program configured to autoload at powerup.
•••
S:35 Status Last 1 ms Scan Time
The value of this word tells you how much time elapsed in a
program cycle. A program cycle includes the ladder
program, housekeeping, I/O scan, and servicing of the
communication port. This word value is only updated by the
processor once each scan, immediately preceding the
execution of rung 0, file 2 (or upon return of a REF
instruction).
