4.2. CC-Link version discrepancy

The discrepancy between the version of the CC-Link supported by BD570 or BD58A of the Hi5 controller and the version of the CC-Link set for the CC-Link master of a controller of higher class, such as the process PLC or PC, means that communication will not take place normally.

Table 4-2 shows how to identify the discrepancy between the version of the CC-Link of the CC-Link master and the version of the CC-Link of the Hi5 controller.

Table 4‑2 CC-Link version discrepancy

CC-Link version		State		Remarks
Master	Hi5
V2.0	V1.0	Master	ERR LED turned on
		Hi5		Before resetting the master
				After resetting the master
V1.0	V2.0	Master	ERR LED turned off
		Hi5

※ The CC-Link communication state of the Hi5 controller can be checked by entering 『[F2]: System』 → 『2: Control parameter』 → 『2: Input/Output signal setting』 → 『11: BD57x fieldbus(CC-Link) information』.
