Host Link Systems
Both Error flags and Restart bits are provided for Host Link Systems. Error flags
turn ON to indicate errors in Host Link Units. Restart bits are turned ON and then
OFF to restart a Host Link Unit. SR bits used with Host Link Systems are summa-
rized in the following table. Rack-mounting Host Link Unit Restart bits are
not effective for the Multilevel Rack-mounting Host Link Units. Refer to the
Host Link System Manual for details.

PC Link Systems
When the PC belongs to a PC Link System, words 247 through 250 are used to
monitor the operating status of all PC Link Units connected to the PC Link Sys-
tem. This includes a maximum of 32 PC Link Units. If the PC is in a Multilevel PC
Link System, half of the PC Link Units will be in a PC Link Subsystem in operating
level 0; the other half, in a Subsystem in operating level 1. The actual bit assign-
ments depend on whether the PC is in a Single-level PC Link System or a Multi-
level PC Link System. Refer to the PC Link System Manual for details. Error and
Run Flag bit assignments are described below.
Bits 00 through 07 of each word are the Run flags, which are ON when the PC
Link Unit is in RUN mode. Bits 08 through 15 are the Error flags, which are ON
when an error has occurred in the PC Link Unit. The following table shows bit
assignments for Single-level and Multi-level PC Link Systems.
