LEGACY I/O SUPPORT
7.1
RS-485 I/O Support
The CTI Janus controller supports CTI 2500 2500® Series I/O, Siemens Series 505® I/O and Siemens Series 500® I/O
products.
7.1.1
CTI 2500 Series I/O Support
The Janus controller supports all current CTI 2500 Series® discrete and analog I/O modules. Both CTI 2500 Series
Classic I/O modules and CTI 2500 Series Compact I/O modules are supported. When using the Janus 2500P-Jxxx
controller, Classic I/O modules can be installed in the same base as the Janus controller or installed in a remote
base connected to the controller via an RS-485 cable. Compact I/O modules must be installed in a Compact remote
base.
CTI 2500 Series Special Function modules are currently not supported. However, due to the enhanced
communication capabilities of the Janus controller, Ethernet-based special function modules are no longer
necessary.
The controller can communicate with the following CTI 2500 Series Remote Base Controllers:
•
CTI 2500-RIO-A and 2500-RIO-B remote base controllers (Classic)
•
CTI 2500C-RBC-485 remote base controllers (Compact).
7.1.2
Siemens 505 and Series 500 I/O Support
The CTI Janus controller supports most current Siemens Series 505 discrete and analog I/O modules. Special
function modules are not supported. The CTI Janus controller also supports designated Siemens Series 500 discrete
and analog I/O modules.
Janus Workbench
will present a list of supported modules during configuration.
The controller can communicate with the following Siemens series 505 remote base controllers:
•
505-6851 and 505-6851A (RS-485)
•
505-6850 and 505-6850A (Coax)
When using SIMATIC 505-6850 or 505-6850A remote base controllers, you must attach the RBC to the Janus
controller using a Siemens SIMATIC 505-6860 I/O Channel Converter.
The CTI controller will communicate with Siemens Series 500
®
I/O installed in a remote base using the following
Remote Base Controllers:
•
500-5114 and 500-5114A (RS-485)
•
500-2114 and 500-2114A (Coaxial)
When using a 500-2114 or 500-2114A, you must attach the RBC to the CTI Janus controller using a Siemens 505-
6860 I/O Channel Converter.
