NOTE: All Schedule commands accept as optional arguments a list of antennas to which the command should selectively sent. Accepted syntaxes are:
= EOVSA Schedule Commands =
Command ant1 ant2 ant3
Command ant1-3
Command subarray1
Command subarray2
If no antenna list is indicated, the command is sent to all antennas currently in subarray1


== Commands handled directly by ACC ==
This page documents the **Schedule Commands** used by the EOVSA Monitor & Control system to operate antennas, front-end electronics, digital control modules, frequency synthesizers, and safety monitors.


'''ABORT'''
----


Aborts all commands sent to ACC but not yet executed
== General Notes ==


'''CLEAROFF [antenna list]'''
=== Antenna List Syntax (Optional) ===


Sets all AzEl or RaDec offsets to zero
All Schedule commands accept an optional **antenna list** specifying where the command should be sent.


'''DCMATTN HPOLattn VPOLattn [antenna list]'''
Accepted syntaxes:
<pre>
COMMAND ant1 ant2 ant3
COMMAND ant1-3
COMMAND subarray1
COMMAND subarray2
</pre>


Indicates the VPOL and HPOL attenuations for the DCM modules indicated in the list. The attenuations are applied on the next second start.
If no antenna list is provided, the command is sent to **all antennas currently in subarray1**, unless explicitly noted otherwise.


<span style="color: red">Warning:</span>The command is executed only if the DCM modules are in manual mode (see the DCMAUTO-ON and DCMAUTO-OFF command below)
----


'''DCMAUTO-OFF [antenna list]'''
== Commands Handled Directly by ACC ==


Sets the DCM modules in the manual attenuation mode. This mode allows the attenuations requested by the DCMATTN to be applied.
=== Command Execution Control ===


'''DCMAUTO-ON [antenna list]'''
; ABORT
: Aborts all commands sent to ACC but not yet executed.


Sets the DCM modules in the automatic attenuation mode. This mode ignores the manual DCMATTN commands and applies the attenuation set through the DCMREGIME mechanism.
----


'''DCMOFFSET level1 level2…..level50'''
=== Pointing Offsets ===


Sets the 50 DCM regime states to be cycled during each second, starting with the next second boundary. The command expects up to 50 arguments. If fewer arguments are provided, the existing set is repeated in the same sequence until all 50 slots are filled. This command is only intended for testing. During normal operations, the DCMREGIME states are requested by the DPP computer.
; CLEAROFF [antennalist]
: Clears all Az/El or RA/Dec offsets.


<span style="color: red">Warning:</span> The command is executed only if the DCM modules are in auto mode (see the DCMAUTO-ON and DCMAUTO-OFF command below).
----


NOTE
== Digital Control Module (DCM) Commands ==


The DCMREGIME settings are changed on the edge of the next second after a TCP/IP message is received by ACC at the TCP.dpp.port  (default port: 6344-set in ACC.ini file ). The message is expected to be a fixed length binary string having the following format
=== DCM Operating Mode ===


<pre>REGIME + blank space + 50 32bit integers (I32)</pre>
; DCMAUTO-OFF [antennalist]
: Sets DCM modules to '''manual attenuation mode''', allowing '''DCMATTN''' commands to be applied.


'''DCMTABLE  [antennalist] filename'''
; DCMAUTO-ON [antennalist]
: Sets DCM modules to '''automatic attenuation mode''', ignoring '''DCMATTN''' and applying offsets via the '''DCMOFFSET''' mechanism.


Request the antenna list portion of a specific DCM base attenuation table to be uploaded on the respective DCM modules. The DCM table must have 30 columns and 50 rows, each pair of adjacent columns listing the HPOL-VPOL pairs for each of the 50 slots of a tuning sequence. The DCM table text file must be located in the ACC “c:\parm” directory and its default name is “DCM.txt”.
----


The DCM/table_timeout key in the ACC.ini files have to be manually edited in order to modify the default timeout (ms) of the DCM modules when a table is broadcasted.
=== Manual DCM Attenuation ===


The actual DCM attenuations for a given tuning slot are calculated based on the following formula
; DCMATTN HPOLattn VPOLattn [antennalist]
: Sets HPOL and VPOL attenuations for the listed DCM modules.
: Applied on the next second boundary.


<pre>atten[pol,tuning_index]=base_atten[pol,tuning_index]+regime*2db</pre>
'''Warning''': Executed only when DCM modules are in '''manual mode'''.


'''DPPOFFSET-OFF'''
----


Ignores DCM offset attenuation recommendations sent by DPP but still allows setting the offsets via the DCMOFFSET schedule command.
=== DCM Offset Attenuation (Testing / DPP Interaction) ===


'''DPPOFFSET-ON'''
; DCMOFFSET inc1 inc2 … inc50
: Defines up to 50 attenuation offset increments to be cycled once per second.
: If fewer than 50 values are provided, the sequence is repeated.
: Intended only for testing.


Applies DCM offset attenuation recommendations sent by DPP but still allows setting the offsets via the DCMOFFSET schedule command.  
'''Warning''': Executed only when DCM modules are in '''automatic mode'''.


<span style="color: red">NOTE: This is the default behavior of the system after each hardware ACC reboot or after a REBOOT or RESET command is sent via TCP/IP to the emergency 6543 acc.solar.ini port</span>
'''Binary message format (DPP → ACC):'''
* TCP/IP port: TCP.dpp.port (default '''6344''', defined in ACC.ini)
* Payload: 50 × 32-bit signed integers (I32)


'''FEM-INIT'''
----


Initialize all front-end module base attenuations with the values read from the ACC initialization file: “c:\ni-rt\startup\acc.ini”.
; DCMOFFSET-CLEAR
: Clears the current list of 50 DCM offset attenuations.


'''FEMATTN level [antennalist]'''
'''Warning''': This clears offsets for '''all''' DCM modules.


Manually selects the front-end attenuation levels for the antennas indicated in the list to be applied on the next second boundary. The attenuation level selects the corresponding entry in the “c:\parms\FEMATTN.txt” attenuation FEM table located on each the cRIOs.

EOVSA Schedule Commands

This page documents the **Schedule Commands** used by the EOVSA Monitor & Control system to operate antennas, front-end electronics, digital control modules, frequency synthesizers, and safety monitors.

General Notes

Antenna List Syntax (Optional)

All Schedule commands accept an optional **antenna list** specifying where the command should be sent.

Accepted syntaxes: 

COMMAND ant1 ant2 ant3
COMMAND ant1-3
COMMAND subarray1
COMMAND subarray2

If no antenna list is provided, the command is sent to **all antennas currently in subarray1**, unless explicitly noted otherwise.

Commands Handled Directly by ACC

Command Execution Control

ABORT
Aborts all commands sent to ACC but not yet executed.

Pointing Offsets

CLEAROFF [antennalist]
Clears all Az/El or RA/Dec offsets.

Digital Control Module (DCM) Commands

DCM Operating Mode

DCMAUTO-OFF [antennalist]
Sets DCM modules to manual attenuation mode, allowing DCMATTN commands to be applied.
DCMAUTO-ON [antennalist]
Sets DCM modules to automatic attenuation mode, ignoring DCMATTN and applying offsets via the DCMOFFSET mechanism.

Manual DCM Attenuation

DCMATTN HPOLattn VPOLattn [antennalist]
Sets HPOL and VPOL attenuations for the listed DCM modules.
Applied on the next second boundary.

Warning: Executed only when DCM modules are in manual mode.

DCM Offset Attenuation (Testing / DPP Interaction)

DCMOFFSET inc1 inc2 … inc50
Defines up to 50 attenuation offset increments to be cycled once per second.
If fewer than 50 values are provided, the sequence is repeated.
Intended only for testing.

Warning: Executed only when DCM modules are in automatic mode.

Binary message format (DPP → ACC):

  • TCP/IP port: TCP.dpp.port (default 6344, defined in ACC.ini)
  • Payload: 50 × 32-bit signed integers (I32)
DCMOFFSET-CLEAR
Clears the current list of 50 DCM offset attenuations.

Warning: This clears offsets for all DCM modules.

DCM Base Attenuation Tables

DCMTABLE [antennalist] filename
Uploads a DCM base attenuation table to the listed antennas.

Table requirements:

  • 30 columns × 50 rows
  • Adjacent column pairs represent HPOL/VPOL
  • File location: c:\parm\
  • Default filename: DCM.txt

Timeout behavior is controlled by the DCM/table_timeout key in ACC.ini.

Attenuation formula: 

DCM_atten[pol,slot] =
    DCM_base_atten[pol,slot] + DCM_offset[broadcasted]

DPP Offset Interaction

DPPOFFSET-ON
Applies DPP-recommended offset attenuations while allowing manual DCMOFFSET.

Warning: Once in the service position, antennas should be placed in local mode.


SERVICE-OUT antennalist
Updates the list of antennas placed into service mode by deleting the antennalist from the existing list.
