CTNet is a de-centralised "peer-to-peer" system, requiring no master PLC controller, with each node taking its turn to control the network, and communicate directly with other network nodes.   Key Features - Supplied as the large option module - Fully UD70 functionality is retained, allowing a fully distributed control system to be implemented - Supports data rates up to 5.0 Mbits/sec   - "Peer-to-peer" communications system allows every node to transmit data to other nodes on the network - No master controller required. Co-proccesor provides local intelligence using SYPT programs. - "Easy Mode" set-up allows cyclic data transfer of upto 3 parameters in and out, to be configured using drive parameters from keypad - Full cyclic and non-cyclic transfers are configurable from SYPT - Fast cyclic data channel, transmits data on a configurable timebase, ranging from 1 ms to 99 ms - Slow cyclic data channel, transmits data every 2 to 19 cycles of the fast data channel - Up to 10 cyclic data links may be defined per node - Non-cyclic data channel allows aperiodic communications between any two nodes - Cyclic and non-cyclic data can be "broadcast" to all other nodes - Up to 20 registers may be transferred on a single fast or slow data link   Specifications Network - RS485 transformer-isolated physical layer - Data rates from 1.25 Mbits/sec to 5.0 Mbits/sec - Up to 100m network length at 5.0 Mbits/sec - Up to 200m network length at 2.5 Mbits/sec - Up to 20 nodes without network repeaters   Environment - Ambient Temperature: -5ºC to +40ºC - Storage Temperature: -40ºC to +50ºC - Weight: 172g - Maximum Altitude: 4000 m - Humidity: +5% to +95% at 40ºC non-condensing
