Chapter 6 : Model 2608 Analog I/O Module

6.5 Reset

Upon module reset, all analog input channels default to low

gain and all analog outputs switch to zero volts out. A 2608

module will experience a module reset in response to any of

the following conditions:

• Module power-up.

• Watchdog time-out due to soft or hard fault.

• SoftReset or HardReset action request from the client.

• Communication time-out, which will occur if the client

fails to communicate with the DIO module within a

programmable communication watchdog interval.

6.6 Actions

This section describes the programmable actions that are

supported exclusively by AIO modules. These actions may be

employed, in any sequence or combination, in MCmd action

lists. In addition to the actions listed here, the AIO module

also supports all of the common actions that are universally

supported by all IOMs.

Note: Model 2608 has a maximum MRsp size of 38 bytes.

6.6.1 SetOutput

Function Programs the output setpoint of one analog

output channel.

Opcode 0x00

Command (Chan),(Value<7:0>),(Value<15:8>)

Value, which specifies the exact value that will

be written to the DAC, is not corrected for DAC

gain and offset errors. The following table

illustrates the approximate relationship between

the Value parameter and the resulting output

voltage.

Response none

Notes Although the action response is generated

immediately, the actual updating of the analog

output is deferred. The analog output will be set

to its target output voltage within two

milliseconds after this action executes.

All analog output setpoints default to zero in

response to a module reset, causing all analog

outputs to produce zero volts out.

6.6.2 GetOutput

Function Returns the programmed output setpoint of one

analog output channel.

Opcode 0x01

Command (Chan)

Table 14: Summary of Model 2608 Actions

Command Opcode Function

SetOutput

Parameter Function

Chan Analog output channel to be

programmed. Values may range from

0 to 3, inclusive. The six high-order

bits should be zero for future

compatibility, but are ignored in this

version.

Value Signed, 16-bit value, LSB first, that

specifies the output setpoint for the

target analog output channel.

Value Output Voltage (V)

0x0001 + 0.0003052

0x7FFF +10.0000

Parameter Function

Chan Analog output channel to be addressed.

Values may range from 0 to 3,

inclusive. The six high-order bits

should be zero for future compatibility,

but are ignored in this version.
