<-- S10F4 Acknowledge sent and text displayed.

Operator reads message and presses button

<-- S6F11

[IF] Acknowledge Terminal Message event

enabled [THEN] send event report

5.9 Error Messages

This capability provides reporting of communications link errors to the host. All of the stream 9

messages as define in SEMI standard E5 are supported. The message structures are included in

section 4.9.

5.10 Clock

The DEK printer maintains an internal, host viewable, clock that is used for event report time

stamps. In order to differentiate between near simultaneous events, the clock has a precision of

0.01 seconds. It is not guaranteed to be accurate to the same level.

Note that the host must use the set time message S2F31 to synchronise the equipment. This

message contains the TIME variable defined in the machine variables, which has a precision of

1 second when the 12 byte format is used. When the 16 byte format is used it has a precision of

0.01 of a second. The format that is in use depends on the value of variable TimeFormat.

Scenarios:

Host requests that the equipment time is set:

Comments Host Equipment Comments

Set time TIME = Host time S2F31 -->

Adjust equipment to host time offset.

<-- S2F32 Acknowledge new time.

Host requests equipment current time:

Comments Host Equipment Comments

Time request S2F17 -->

<-- S2F18 Value TIME = host offset time sent.

5.11 Limits Monitoring

The DEK printer is capable of monitoring limits on selected status variables and discrete variables.

These variables are identified in section 5.5. The printer provides seven configurable limits that may be

applied to each variable. When one of these limits is crossed a collection event is generated. The event

can be used to alert the host that the variable has crossed a limit.

5.11.1 Definitions

Limit - Used in this section to represent the set of variable limit attributes that completely describe a

variable monitoring "barrier." The attributes include VID, Units, UPPERDB, LOWERDB,

LIMITMAX, and LIMITMIN. In some contexts it may be interpreted more narrowly as the

combination of UPPERDB and LOWERDB.

LIMITIDn - Refers to the identifier of a specific limit (as defined by UPPERDB and LOWERDB)

among the set of limits for a monitored equipment variable. LIMITIDs are consecutively numbered,

beginning at one through the number of limits possible (seven minimum).

Monitoring Zone - A subset of the possible range of values for a variable of interest to the host. A

single limit divides the range into two zones. Multiple limits may be combined to divide the range even

further.

Zone Transition - The movement of a variable value from one monitoring zone to another. This

transition is a collection event and has a corresponding CEID.

Deadband - An overlap of two zones implemented to prevent constant zone transitions by a variable

sitting on or near a limit (i.e. "chattering").

UPPERDB - A variable limit attribute that defines the upper boundary of the deadband of a limit. The

value applies to a single limit (LIMITID) for a specified VID. Thus, UPPERDB and LOWERDB as a

pair define a limit.

LOWERDB - A variable limit attribute that defines the lower boundary of the deadband of a limit.

The value applies to a single limit (LIMITID) for a specified VID. Thus, UPPERDB and LOWERDB

as a pair define a limit.

UPPER ZONE - The range of values lying above a limit.

LOWER ZONE - The range of values lying below a limit.

LIMITMAX - The maximum value for any limits of a specific equipment variable. This value is set

by the equipment manufacturer and typically coincides with the maximum value allowed for the

monitored variable.
