	Items		Specifications

Communications method		N:N token bus

Code		Manchester code

Modulation		Baseband code

Synchronization		Flag synchronization (conforms to HDLC frames)

Transmission path form		Multi-drop bus

Baud rate and maximum		The maximum transmission distance varies with the baud rate as follows:
transmission distance		2 Mbps:	500 m

		1 Mbps:	800 m
		500 Kbps: 1 km

Media		Specified shielded twisted-pair cable
		Number of signal lines: 2, shield line: 1

Node connection method		PLC: Connected to a terminal block
		IBM PC/AT or compatible: Connected via a special connector (included)

Maximum number of nodes		32 or 62 nodes (See note 2.)

Communications functions		Data links and message service

Number of data link words		Transmission area per node: 1,000 words (2,000 bytes) max.
		Data link area (send/receive words) per node
		CS/CJ Series: 20,000 words max. (unit Ver. 1.2 or later)
			12,000 words max. (pre-Ver. 1.2)
		C200HX/HG/HE, CVM1/CV, CQM1H: 8,000 words max.
		Personal computer: 32,000 or 62,000 words max. (See note 3.)
		Number of data link words in one network (total transmission):
			32,000 words (64,000 bytes) or 62,000 words max. (See note 3.)

Data link areas		Bit-access areas (IR, AR, LR, CIO), DM Area (DM), and extended DM Area (EM)

Message length		2,012 bytes max. (including the header)

RAS functions		Polling node backup function
		Self-diagnosis function (hardware checking at startup)
		Echoback test and broadcast test (using the FINS command)
		Watchdog timer
		Error log function

Error control		Manchester code check
		CRC check (CCITT X16 + X12 + X5 + 1)

Note 1. The maximum distance between nodes depends on the connector and ca- ble processing methods.

2.At least one Repeater Unit is required to construct networks that uses a node address higher than 32. The following Controller Link Units/Support Boards must also be used, and the Wired Network 62 Node Enable Bit of the DM Parameter Area software switch of all nodes must be turned ON (62 nodes max.).

CS1W-CLK21-V1, CJ1W-CLK21-V1, and 3G8F7-CLK21-V1

3.62,000 data link words applies to configurations of 62 nodes.
