Key issues

Question 1: What is the core difference between AFV40S and AFV40D? How to select based on project redundancy requirements?

answer

Core Differences:

Redundancy configuration: AFV40S is single redundancy (optional dual redundancy for processor/power/ESB bus), AFV40D is full dual redundancy (mandatory dual redundancy for processor/power/Vnet/IP/ESB bus);

Suffix restrictions: AFV40D only supports dual redundancy related suffixes (such as ESB bus with only 2/4 options), while AFV40S supports single/dual redundancy suffixes;

Node Unit: AFV40S supports single/dual power node units, while AFV40D only supports dual redundant ESB+dual power node units (ANB10D-4  5).

Selection principle:

High reliability requirements (such as critical process control): Choose AFV40D, fully redundant configuration to avoid single point of failure;

Cost sensitive and non critical scenarios: Choose AFV40S and configure single/dual redundant ESB buses and power supplies as needed;

Number of nodes ≤ 9: AFV40S with EC401; Number of nodes 10-11: AFV40S with EC402, AFV40D with EC402.

Question 2: What are the key rules for unit installation and fan configuration in the AFV40 cabinet? How to avoid installation violations?

answer

Unit installation rules:

Quantity limit: A maximum of 11 units (ANB10 +ANT10U) can be installed in the cabinet, with ≤ 5 units in the front and ≤ 6 units in the rear;

Installation sequence: ANB10  node unit must be installed first, followed by ANT10U optical relay unit;

Cable connection: The ESB bus cable (YCB301) inside the cabinet has been pre installed, and manual connection is required between ANB10  and ANT10U.

Fan configuration rules:

The number of node fans (ANFAN) is configured according to the total number of units (0-4 → 1, 5-9 → 2, 10 → 3, 11 → 4);

Door fans are standard configuration (4 units), no additional selection is required.

Avoid violations:

Install strictly in the order of "ANB10  priority", without reversing unit types;

Accurately select fan option codes based on the total number of units, without omission or excessive configuration;

The optical ESB node needs to be connected through the ANT401/ANT411 relay module, not directly connected to the FCU.

Question 3: What are the communication interface and power configuration options for AFV40? How to adapt to different on-site power supply conditions?

answer

Communication interface selection:

Vnet/IP interface: dual redundant configuration (AFV40S can provide a single power supply, AFV40D requires dual power supply), used for system control network;

ESB bus interface: AFV40S can be selected as a single menu (EC401/EC402 × 1) or dual redundancy (EC401/EC402 × 2), AFV40D is mandatory dual redundancy, used to connect node units;

HK bus interface: single channel, used to connect external cabinet HKU, total length ≤ 100m.

Power configuration selection:

Power supply type: Supports 100-120V AC (50/60Hz), 220-240V AC (50/60Hz), 24V DC, specified by suffix code;

Power redundancy: AFV40S can provide single/dual power supply, while AFV40D requires dual power supply.

On site adaptation plan:

Conventional industrial power supply (220-240V AC): choose suffix "2", AFV40S can be a single power supply (suffix "3") or a dual power supply (suffix "4");

Low voltage scenario (24V DC): Select suffix "4" and confirm that the on-site DC power supply capacity is ≥ 71A;

Cross border project: Select option code "/CE" to obtain CE/RCM/ECC/KC multi certification adaptation;

Explosion proof scenario: Select option code "/ATDOC" to obtain the ATEX Directive Adaptation Manual.
