Creating Chains

required frequently, to avoid using the same system commands over and over. You can also create a series of

displays which show more detailed information about a monitored area or item of equipment. Each group of related

displays is called a "Chain" and each display within a chain is called a "Link". The number of chains and links that

can be used is defined in the operator profile; however, a maximum of 16 chains and 32 links are possible.

(1) Creating Chains. Chains are created when requesting a primary display by using any of the available

options, such as a Display Menu, except for the cursor option. Each new chain created is assigned the next available

serial number until the maximum allowable number of chains is reached. The first chain created is identified as "Chain

1", the second is identified as "Chain 2", etc. In addition, the first display in each chain is designated as "Link 1".

NOTE

If you use all available chains, and then request a display that requires another chain to be created, the

oldest chain is deleted and the new display becomes link 1 of that chain.

(2) Adding Links. Links can be added to chains using the cursor option at the correct state in creating a

primary display. Each new link is assigned a serial number (for example, link 2, link 3, etc.) which indicates its position

within the chain. Links can be created by cursoring either the last display in a chain or any intermediate display (that is,

one that has previously been cursored). However, in the latter case, the system deletes links that follow the display being

cursored. For example, if a chain contains five links and you page back to and cursor link 3, your new display becomes

link 4. Your previous link 4, along with link 5, is deleted.

(3 Paging. When a number of links have been created, they can be paged through using the [NEXT PAGE]

and [PREV PAGE] keys. When paging forward, the system displays either the next link in the current chain or, if the end

of the chain has been reached, the last link in the next chain.

(4) Deleting Links. Links can be deleted by calling a current display, holding down [CODE], and pressing

[DELETE]. If this is done when Link 1 of a chain is displayed, the current link and all following links are deleted.

k. Scrolling Displays. Except for graphics, each primary display created is stored in an independent file. The

information within each file depends on the nature of the display and the search criteria on which the file is based. When

a display is created, the system puts as many entries as possible within the display frame, beginning from the top of the

file, and inserts the word End on the last line of the file to indicate that no other entries exist.

(1) Scrolling Up/Down. Scrolling is used for moving a display up or down in the display frame to bring a

particular part of a file into view. Press the [SCROLL UP] key to move the display up. To scroll a display downwards,

press the [SCROLL DOWN] key.

(2) Repeat. Both of the scroll keys repeat when held down for longer than a half second.

I. Silencing the Audible Alarm Tone. The workstation audible alarm draws your attention to changes occurring

within the alarm frame. The alarm tone is sounded at 5 second intervals until it is acknowledged, cleared, deferred, or

silenced by using one of the options below.

(1) Two keying options for silencing the tone are [FINISH] and [CODE]-[FINISH]. You can use either option to

suppress the tone until the next change occurs.

(2) As an alternative, you can suppress the tone for a time period defined in your operator profile record by

pressing [SHIFT]-[FINISH].
