Features

Section 1-1

1-1 Features

•The CQM1-B7A@@ Interface Unit incorporates the B7A transmission operations for the CQM1H/CQM1 I/O Unit.

•The following five models of CQM1H/CQM1 B7A Interface Unit are available.

Model		No. of points
		Input	Output
CQM1-B7A21	16		16
CQM1-B7A13	32		0
CQM1-B7A03	0		32
CQM1-B7A12	16		0
CQM1-B7A02	0		16

Differences Between

CQM1-B7A01 and

CQM1-B7A21

•Each Unit can be connected to the same number of points on 16-point B7A Link Terminals as provided by the Unit. For example, two B7A Link Terminal Units with 16 input points each can be connected to a CQM1B7A13.

•The transmission delay time can be switched between STANDARD (19.2 ms rated) or RAPID (3 ms rated).

•The data processing when a transmission error occurs can be switched between HOLD (see note 1) and LOAD OFF (see note 2).

•The CPU treats the B7A Interface Units as the equivalent number of points. It can handle remote I/O equipment, such as switches and lamps, without recognizing communications.

Note 1. HOLD: When an error occurs, the input bit status immediately prior to the error is held.

2. LOAD OFF: When an error occurs, all input bits turn off.

The B7A Link Terminal is a terminal board that incorporates a communication function, connects to external I/O devices, and communicates with a PC over a single cable, thus reducing wiring effort.

CQM1-B7A21 is an upgraded version of the CQM1-B7A01 and can replace the CQM1-B7A01.

The features listed in the table below have been added to the CQM1-B7A21.

the CPU to the B7A Interface Unit’s output bit is larger than the above values.
If smaller than the above values, data might not be correct transmitted.

Transmission Errors

Power On	If the input mode is set to 15IN+ERR, the transmission error bit becomes OFF
	when the CQM1H/CQM1 power is turned on.
	The transmission error bit turns ON if normal transmission with the input B7A
	Link Terminal is not established within 10 ms.
	All input bits remain OFF from the time CQM1H/CQM1 is turned on until nor-
	mal transmission is established.

Bit Allocation	Section 1-5
Inputs	When a transmission error occurs, the input bits are processed according to
	the transmission error processing setting: HOLD or LOAD OFF.
	If the input mode is set to 15IN+ERR, the transmission error bit turns ON.
	The transmission error bit turns OFF when normal transmission is re-estab-
	lished.
	The normally received signals are then input to the input bits.
Outputs	A transmission error with an output B7A Link Terminal can only be detected at
	the Link Terminal. Confirm the error with the Link Terminal ERR indicator and
	error output.
