Name

actSRtask - ACT status read module I/O service

Synopsis

actSRtask <argument list>

Description

Status read I/O service for ACT modules.

This program supports all digital input ACT modules.

Base modules consist of 16 channels. Expansion (or mezzanine) modules contain 8 channels and can be installed only on digital base modules (input or output).

An input is considered on when a voltage between 3 and 30VDC or up to 30VAC peak-to-peak is applied.

Arguments

Argument processing is done using Unix long argument syntax.

The values of all the parameters listed here (whether or not they were supplied on the command line) are printed on stderr when the program starts.

--dbman_host <hn>

The host where dbman is running.

If this argument is not supplied the default is "localhost".

The DBMAN_HOST environment variable is used if present.

--dbman_name <rn>

Sets the name the program will use to register with dbman.

--dev <path>

The device path to open.

If this argument is not supplied the default is "/dev/kbuss".

--drv <drv>

The driver key to use.

If this argument is not specified the default is "KBUSS_1".

--cmin <C>

The minimum crate number.

If this argument is not supplied the default is "0".

--cmax <C>

The maximum crate number.

If this argument is not supplied the default is "15".

--log_flag <logging>

If this argument has the value "bad", I/O trasactions with bad status will be logged each time the status changes.
If this argument has the value "all", I/O trasactions will be logged whenever the binary data value changes.

--diag

Don’t close stdin and stdout and allow SIGINT to kill the program.

--show_tbl

Print the contents of various tables to stderr.

--verbose=<level>

Print more information. If <level> is missing it defaults to 1.

--persist

Run the program in persist mode.

--tagname_ctl

parameter name to use for task control.

--tagname_status

parameter name to use for reporting task status.

--help

Print the help information to stderr.

Device Types used by this program

ACTsrV - required

Status Reads. This record must be present in the database for the module to be serviced by the program.

DTkey should always be set to U.

Crate defines the module’s address.

Slot defines the channel count.
0 = 8 Channels
1 = 16 Channels
2 = 24 Channels

ChanNo should always be set to 0.

Each bit is mapped the the corresponding channel offset on a given module.

I/O polling rates

Polling is normally performed at 1Hz.
Fast polling at 10Hz is supported.

Examples

#
# this example limits service to address 0 thru 3
# dbman is running on the same host
#

actSRtask --cmin 0 --cmax 3
