53
Crossload Status. This is a Message instruction error code. The
processor writes the value into this word. For information on error
descriptions, refer to your PLC-5 Instruction Set Reference Manual.
54
Crossload Failed File. This word displays the file number on which the
crossload failed. The crossload status word located in word 53 displays
the error code and word 54 displays its correlated file.
55
User-Defined Crossload File 1. You can select a single file number,
written in this word, to be crossloaded during the Qualification crossload,
and on-demand when setting the appropriate bit in word 33.
56
User-Defined Crossload File 2. You can select a single file number,
written in this word, to be crossloaded during the Qualification crossload,
and on-demand when setting the appropriate bit in word 33.
57
User-Defined Crossload Range Low File. You can select a range of files
to be crossloaded during the Qualification crossload, and on demand
when setting the appropriate bit in word 33. The lower file number of
the range of files to be crossloaded must be written into this register.
58
User-Defined Crossload Range High File. You can select a range of files
to be crossloaded during the Qualification crossload, and on demand
when setting the appropriate bit in word 33. The higher file number of
the range of files to be crossloaded must be written into this register.
59-64
The secondary time/date stamp of when the processor last took over as
secondary processor. The format of the date is the same as the system
clock in the status file.
65-68
These words are functionally the same as words 55 through 58. The
difference is that these words display the current PLC-5 processor state
of these configuration parameters. When in Run mode, the processor
continuously updates words 65 through 68. In other words, new
configuration parameters are written into words 55 through 58, while the
PLC-5 processor writes its internal state of these configuration
parameters into words 65 through 68. When you accept a configuration,
the configuration parameters in words 55 through 58 are copied into
words 65 through 68.
69
reserved
70
Crossloading over Data Highway Plus. Set the value in word 70 of the CBI
file:
0 = Crossload over Channel 2 (ControlNet - default)
1 = Crossload over Channel 1A (DH+)
71
Crossload status
72
Requalification of Dual Primary Programmable Controllers. Set the value
in word 72 of the CBI file:
0 = No requalification with dual primary (default)
1 = Requalification with dual primary
73
Requalification status
