Emerson DM6361 Discrete Input Card

Logic Solvers (SLS 1508) contain the logic-solving capability and provide an interface

to 16 I/O channels that can be configured as Discrete Input, Discrete Output, Analog Input

(HART) and HART two-state output channels. Logic Solversand termination blocks

install on the 8-wide carrier.

Logic Solvers communicate with each other through thecarriers over a two-channel,

local peer bus (SISnet) and remotepeer ring. Local Logic Solvers are hosted by the same DeltaV

controller and remote Logic Solvers are hosted by a different DeltaV controller.

Logic Solvers are powered by a 24 V DC power supply that is separate from the

power supply that drives the DeltaV controller and I/O. Logic Solvers install

in odd-numbered slots (1.3.5.7) on the 8-wide carrier.

System Compatibility

M-series I/O carriers are not physically compatible with

S-series controller carriers, except when used with the

DeltaV SIS Adapter.

The M-series controllers cannot detect the difference between

an 8-wide and a 4-wide carrier. If a 4-wide carrier is used,

the four I/O slots after the slots on the carrier will be lost to

an M-series controller. If either a 4-wide or 8 wide carrier is

connected after a 4-wide carrier, the first slot number will

be 5 numbers higher than the last slot on the 4-wide carrier.

For example, if a controller has a 4-wide carrier followed by

an 8-wide carrier, the slots on the 4-wide carrier will be

1. 2. 3. and 4. and the slots on the 8-wide carrier will be

slots 9. 10. 11. 12. 13. 14. 15. 16. The PK Controller does

not have this behavior because it can distinguish between

a 4-wide and an 8-wide carrier. However, there is still a limit

of 8 total carriers (4-wides and/or 8-wides) on any controller.
