Interpretation of Omron CP series PLC family

When using Omron's small CP series family PLC, many people cannot tell the difference between the various CPU models. Let's explain it below. Omron's CP series PLC is an integrated PLC with built-in pulse output, analog input and output, and serial communication functions. There are mainly 4 products: CP1 E, CP1L, CP1H, and CP2E.

1. CP1E is economical, easy to use, and efficient . It is the lowest cost product in the CP series. Although it is low-priced, it also has built-in high-speed counter function, pulse output function, and serial connection port. In addition, when using expansion units and option boards, it can support various device controls. The disadvantage is that it only supports two-axis pulse high-precision positioning control, and only supports transistor output type when two-axis pulse is used, and does not support FB function blocks and ST text writing.

2 .Features of CP1L Based on CP1E, it has an embedded Ethernet configuration and comes standard with Ethernet communication, which meets the requirements of instruments and equipment that use Ethernet communication. It supports FB function blocks and structured text ST programming. The disadvantage is that it only supports two-axis pulse high-precision positioning control and only supports transistor output type, and its cost price is higher than CP1E.

3. The characteristics of CP1H are that it is equipped with 4-axis pulse input and output and only supports transistor output type, supports Ethernet communication, supports FB function blocks and structured text ST programming. The disadvantage is that it does not have an Ethernet port as standard, and the cost price is higher than CP1E and CP1L.

4. The feature of CP2E is that it integrates functions that meet the needs of small-scale devices, integrates the performance of CP1E, CP1L, and CP1H, enhances connectivity with networks and peripheral devices, is equipped with 2 Ethernet ports, and does not require a switching hub. In addition to upper-level connection, the other end can also be used as a connection to HMI and PLC, a tool connection port, and a standby port, etc. It has a variety of usage methods, supports FB and ST text languages, and supports Ethacat bus. The disadvantage is that compared with other CP series, the cost price is high.
