The 2500P-ECC1 module supports the following communications protocols:

• CAMP Server

• CAMP Client

• Modbus Server

• Modbus Client

• Network Data Exchange

See CHAPTER 2 for information on these protocols.

Using a CTI-supplied configuration program, you can select the protocols to be used and

designate how they will operate. Configuration data is saved on a removable SD memory card,

located on the 2500P-ECC1 circuit board.  If a module ever fails, a replacement can quickly be

placed in service by transferring the SD card from the failed unit to the new one.

Client requests to read data from the 2500 Series® controller are serviced from a data cache

maintained on the 2500P-ECC1 module. The frequency of cache updates is user configurable.

This data cache design allows protocols such as CAMP Server to provide rapid response to a high

volume of requests from SCADA workstations, HMI equipment, and operator panels while

providing a means to manage data quality.
