CTI 2500P-JACP Janus Application Coprocessor

The 2500P-JACP Janus Application Coprocessor is a general-purpose auxiliary

controller that enhances the capabilities of all CTI 2500 Series® and SIMATIC®

505 PLC systems. This Advanced Function Module is based on Janus technology

and includes high-speed processing and multi-protocol communications support

to provide existing systems with a significant increase in performance, features,

and functionality.

Because of its broad communications capabilities and ability to store large amounts

of data on-board, the 2500P-JACP is ideal for Edge Computing applications, bringing

computation and data storage closer to the location where it is needed, to improve

response times and save bandwidth.

The 2500P-JACP runs as a PLC coprocessor performing complex logic/math functions,

data logging, and communications with external devices. Although the 2500P-JACP

can operate as a standalone controller, the control application generally requires data

transfer between a host PLC and the module. Two different data transfer options are

provided:

Block Transfer Driver: The 2500P-JACP enables the user to configure the Block Transfer

Driver which optimizes the exchange of up to 2048 data points with a Siemens, TI, or

CTI PLC using the special function I/O backplane protocol. The application can select to

exchange V, X/Y, WX/WY, or Control Relays for continuous Read or Read/Write.

Note this feature allows the 2500P-JACP to be used with existing Simatic/TI 545 and

555 PLCs.

Data Cache: Proprietary link offering enhanced data throughput to CTI 2500 Series®

controllers via a dedicated Ethernet connection. Supports up to 6144 variables mapped

to any PLC memory type (including Loop/Alarm variables). 

The 2500P-JACP includes two external 10/100/1000Mb Ethernet ports with automatic

detection of network speed, duplex mode, and cable wiring. An aliasing and isolation

feature allows the two network ports to exist on two separate networks, a useful feature

for isolating networks of drives or other I/O devices from the main plant communications

network.
