Bradley Smoker Rack Address, Can only scan rack 3 PLC-5/11 controller, Starting Group, Fault

6-22Communicating with Remote I/O

Status Field	Location Description
Rack Address		This field indicates the rack number of the remote racks being scanned by the scanner channel:
		can only scan rack 3 (PLC-5/11 controller)
		1-3 octal (PLC-5/20, -5/20E controller)
		1-7 octal (PLC-5/30 controllers)
		1-17 octal (PLC-5/40, -5/40L, 5/40E controllers)
		1-27 octal (PLC-5/60, -5/60L, -5/80, -5/80E controllers)
		If complementary I/O is enabled (on the scanner mode configuration screen), the complement of
		a rack is identified with a C to the left of the rack address column on the status screen.
Starting Group		This field indicates the first I/O module group in the rack that the controller scans.
Rack Size		This field displays the portion of the I/O rack addressed by each chassis. Configurations can be
		1/4, 1/2, 3/4, or FULL as long as the total sum of the rack does not exceed 8 I/O groups.
Range		This field displays the rack address and module groups being scanned for a rack in the scan list.
		An asterisk (*) after a range indicates that it is the last valid rack entry.
Fault		An F displayed in this field indicates that the corresponding chassis is faulted. When a fault
		indicator appears, the system sets the associated fault bit in the global rack fault status on the
		controller status screen in your programming software.
		When the global rack fault bit is set, all configuration information starting at the faulted quarter
		is lost. When a rack faults, F is displayed. If both the fault and inhibit bits are set for a rack, no
		rack exists at that I/O group.
Inhibit		Inhibit a rack by cursoring to the Inhibit field of the rack you want to inhibit and enter 1
		When a chassis is inhibited the controller stops scanning it. You can inhibit an entire rack by
		setting the global rack-inhibit bit for that rack on the controller status screen. All chassis within
		that rack are inhibited, and an I appears in the Inhibit field, indicating the rack was globally
		inhibited.
Reset		Reset a rack by cursoring to the Reset field of the rack you want to reset and type 1
		When a chassis is reset, the controller turns off the outputs of the chassis regardless of the
		last-state switch setting. You can reset an entire rack by setting the global rack-reset bit on the
		controller status screen. All chassis within that rack are reset, and an R appears in the Reset
		field indicating the rack was globally reset.
Retry		This field displays the number of times the rack was re-scanned.
