List of Model 204 parameters
Parameters are variables that control or describe Model 204. They can be set to different values to tailor Model 204 operation to the requirements of an installation or user.
Each parameter is described on its own page; links to those pages are included in the table below (click on the parameter name).
One of the key bits of information about a parameter is, "when can it be assigned a new value", or reset, since this is often done using the RESET command. This information is provided for each parameter below.
The table contains an entry for every Model 204 parameter. Some are associated with specific products, such as Fast/Backup, Fast/Reload and many more. Due to this, some parameters may be unavailable at sites not authorized for specific products. Other parameters, while available, don't really do anything unless a site is authorized for specific products. See the "Sirius parameters" footnote below, which describes the availability of parameters marked with (S).

Footnotes
Obsolete parameters
Some parameters were operative in earlier versions of Model 204 but are no longer operative. In order to support compatibility with earlier versions, an obsolete parameter:
- May still be referenced in a VIEW command, but its viewed value should be ignored.
- May be set or reset, but the value will not change, and a warning message is issued indicating this. Hence, an obsolete parameter is, in effect, viewable only.
Further information about the specific obsolescence is contained on each page describing an obsolete parameter.
Sirius parameters
The (S) symbol is shown at the end of the description of each parameter that was provided in the Sirius Mods. These parameters will be unavailable to you if both of these are true:
- You are using a version of Model 204 prior to V7R5.
- You do not have the Sirius Mods included in your Model 204 load module.
