• Communication time-out, which will occur if the client
fails to communicate with the 2652 module within a
programmable communication watchdog interval.
11.5 Status Flags
In addition to the standard flag bits that are common to all
IOMs (see Section 3.4.1), the status byte returned by a 2652
module includes one fault flag that is specific to 2652 module
types. The 2652 status byte is structured as shown in Figure
61.
Figure 61: 2652 Status Byte
STRM - Active-high bit flag that indicates an error was detected
in the serial data stream that is used to control the SSR output
drivers. This flag can be cleared by invoking a ResetFlags
action.
11.6 Actions
This section describes the programmable actions that are
supported exclusively by the 2652 module. These actions may
be employed, in any sequence or combination, in MCmd action
lists.
2652 modules support all of the common actions that are
universally recognized by all IOMs, such as HardReset,
SoftReset
, etc. Refer to Chapter 5 for details.
Note: Model 2610 has a maximum MRsp size of eleven bytes.
11.6.1 GetInputs
Function Returns the debounced, physical channel states of
all SSR channels.
Opcode 0x00
Command none
Response (States)
Notes The returned state values represent the
debounced, physical states of all SSR channels.
Because the inputs are sampled every 2
milliseconds, and the debounce period is 10
milliseconds, the returned state values will all
have an age ranging from 10 to 12 milliseconds,
plus any network communication latency.
Note that the physical states of all SSR channels
are returned, regardless of their respective
operating modes.
11.6.2 GetOutputs
Function Returns the programmed output driver states of
all SSR channels. Note that the programmed
output driver states may not be identical to the
physical channel states (that would be returned
by GetInputs) as some channels may be
driven by external signal sources. In the case of
channels that have been configured for the PWM
mode, this function returns indeterminate state
values.
Opcode 0x01
Command none

Parameter Function
States Bit flags that represent the debounced,
physical states of all SSR channels.
Each bit is associated with one channel.
For example, bit 7 is associated with
SSR channel 7. Any bit set to one
indicates the associated channel is set
to the active state; any bit set to zero
indicates the channel is set to the
inactive state.
Parameter Function
States Bit flags that represent the programmed
output driver states of all SSR
channels. Each bit is associated with
one SSR channel. For example, bit 7 is
associated with SSR channel 7. Logic
one indicates the associated channel is
set to the active state; logic zero
indicates the inactive state.
