EMERSON A6370D/DP Overspeed Protection Monitor

Controlinc Network Master Model M250N contains redundant valve actuator network masters

in a single enclosure. M250N supports one Controlinc E>Net ring network with up to 250 valve

actuators. Options for support of redundant bus networks and redundant E>Net rings are also

available. The supplied system uses standard RS485 and Modbus RTU protocol for the valve

actuator networks. Ethernet TCP/IP encapsulated Modbus protocol connections are provided

for redundant host computer networks. The Ethernet links are IEEE 802.3 with RJ45 connectors

for 10/100Base-TX. Protocol is Ethernet v2 encapsulation TCP/IP Version 4.

Redundant systems consist of two identical chassis with identical software. One is the

primary master and the other a hot stand-by master. The two chassis may switch roles of

primary and hot stand-by at any time. Figure 1 shows the specific system configuration of

the supplied system. The network masters communicate with Controlinc valve actuators

that control both block valves (Open, Stop, Close) and modulating or positioner type valves.

Each chassis consists of two Modbus Slave modules located in Slots 3 and 4. These slave

modules communicate with redundant Modbus host systems up line. The CoProcessor

installed in Slot 1 is the Controlinc Network Master to a ring field network. Two ports of the

Network Master module are connected to Network Interface Module (NIM) Model M124I

with redundant, isolated ports. Each NIM has connections to the redundant Network Master

modules of the redundant chassis. Any one of the four ports may acquire data from and

control all actuators in the field in either direction around the network. Multiple M250N

systems may be networked from a single host or redundant hosts to automate any size

system from a few valves to thousands of valves covering a large network area. Ten (10)

independent processors ensure full redundancy of all functions in a single unit.

The enclosure is rated for NAMA 4/12 and IP65/IP55. Dimensions of the enclosure are shown

in Figure 5. Mounting dimensions are shown in Figure 6. The enclosure may be bulkhead

mounted using the internal mounting holes. External mounting brackets may be used if

desired. When mounting using the internal mounting holes, caution must be used to ensure

the holes are sealed to maintain the NEMA/IP rating. The enclosure is supplied with five 1/2 in.

compression type cable entry hubs. These may be fitted with conduit type fittings if desired.

If the system includes backup LCD keypad terminal, some planning is required to allow for

proper height above the floor to view the display and properly operate the keypad.
