5. Communication Protocols
5.1. MSIV to Field Units
5.1.1. Modbus RTU
5.1.1.1. EIA-485 (RS-485) physical layer
5.1.1.2. Bi-directional redundant loop or multi-drop network topologies
5.1.1.3. Maximum communication rate of 38.4 Kbaud
5.2. MSIV to DCS
5.2.1. Modbus RTU
5.2.1.1. TIA-232 (RS-232) physical layer
5.2.1.2. If RS-485 or RS-422 physical layers are required, an external converter can be specified.
5.2.1.3. Maximum communication rate of 115.2 Kbaud
5.2.2. Modbus TCP/IP
5.2.2.1. 10/100Mbit ethernet physical layer
6. System Redundancy
6.1. A completely modular, redundant system can be setup using two EEP-SN4001 modules.
6.2. Wire the modules in parallel to the same Modbus RTU actuator network and configure one module as
Active and one as Standby.
6.3. The Standby module will monitor network communications and if the Active module fails, the Standby
module will become active and take over the actuator network communications.
