Standard Loader Port on CPU

All CPU models support the RS-232-C 232C loader port via an RJ11 connector. There is no need to configure this port.

The communication parameters are fixed as follows:

• Baud Rate: 38,400

• Parity: None

• Data Bits: 8 bits

This configuration supports only peer-to-peer (1:1) communication. Thus, the CPU ignores the station number in the communication frame from Xpanel. That is, the CPU will accept any station number from Xpanel.

CPU's Option Port

If the CPU’s optional communication port is used for connection with Xpanel, the CPU parameters must be configured as shown below:

Note that the station number (“Station No.“) must be matched with that of the Xpanel configuration. The CP series CPU’s optional port supports two protocols, but there is no need to set the protocol type. This port automatically detects the protocol type.

The following CPU models support the loader protocol on the optional communication port:

• CM1-CP4C or D or U

Communication Module

If one of the following special function modules (options) is used for an Xpanel connection, the card properties should be configured as shown in the picture below:

• CM1-SC01A or B

• CM1-SC02A

• BPnnMxxx-U or T

'Protocol' must be set to ‘CICON(Loader) Protocol’. Ensure that the other communication parameters are matched with Xpanel, especially the station number.
