What is the difference between Panasonic PLC and Mitsubishi PLC?

1, Panasonic PLC: Panasonic PLC is produced by Panasonic Corporation.

2. Mitsubishi PLC: Mitsubishi PLC is the main product produced by mitsubishi electric in Dalian.

Second, the instruction set structure is different.

1, Panasonic PLC: Panasonic PLC programming should pay attention to logical thinking. Programming itself is a logical thinking process. In high-level languages, such as many premise discrimination statements, this is the causal relationship in logic. The PLC program is composed of these causal relationships: judging whether the premise is established, and then judging to execute the corresponding instructions.

2. Mitsubishi PLC: Mitsubishi PLC network inherits the traditional MELSEC network, and Q series PLC provides a clear three-layer network to provide the most suitable network products for various purposes.

Third, the positioning is different

1, Panasonic PLC: 3-axis pulse output function in C14 and 4-axis pulse output function in C30/C60 are built into the main body of the control unit. In the previous PLC, advanced models or special units must be used for position control or more than two multi-axis control devices, while FP-X transistor output products basically only use 1 unit devices, which can save space and reduce costs.

2. Mitsubishi PLC: It improves the expansibility of the product and has a unique dual-bus expansion mode. Using the left bus can expand the connection of analog/communication adapters (up to 4), which has higher data transmission efficiency and simplifies the programming work; The right bus fully considers the compatibility with the original system, and can connect FX series traditional I/O extensions and special function modules.

Matters needing attention in maintenance of Mitsubishi PLC:

A, maintenance procedures, equipment testing and adjustment rules on a regular basis

1. Check the connection of terminals in the PLC cabinet once every six months or once every quarter, and reconnect them in time if they are loose.

2. Re-measure the working voltage of the power supply for the host in the cabinet once a month.

Second, the provisions of the regular cleaning of equipment

1. Clean the PLC once every six months or once every quarter, cut off the PLC power supply, remove the power rack, CPU motherboard and input/output board in turn, purge them, then install them in place in turn, restore all connections, and then power on the PLC host. Carefully clean the sanitary equipment in the PLC box.

2. Replace the filter under the power rack every three months.
