S2F45 Define Variable Limit Attributes (DVLA)
S2F46 Variable Limit Attribute Acknowledge (VLAA)
Description: The host requests the equipment to define the limits for the identified
variables.
A. Host Initiated
Host to equipment: S2F45
Structure: L,2
1. <DATAID>
2. L,m ;m = No. of variables in this definition
1. L,2
1. <VID1>
2. L,n ;n = No. of limits being defined for VID1
1. L,2
1. <LIMITID1>
2. L,p (p = {0,2})
1. <UPPERDB1>
2. <LOWERDB1>
.
.
n. L,2
1. <LIMITIDn>
2. L,p (p = {0,2})
1. <UPPERDBn>
2. <LOWERDBn>
.
.
m. L,2
1. <VIDn>
2. L,n ;n = No. of limits being defined for VIDm
1. L,2
1. <LIMITID1>
2. L,p (p = {0,2})
1. <UPPERDB1>
2. <LOWERDB1>
.
.
n. L,2
1. <LIMITIDn>
2. L,p (p = {0,2})
1. <UPPERDBn>
2. <LOWERDBn>
Exceptions:
1. A zero length list m = 0 sets all limit values for all monitored VID’s to
“undefined”.
2. A zero-length list, n = 0 sets all limit values for that VID to “undefined”.
3. A zero-length list p = 0 sets that limit to “undefined”.

Equipment to host: S2F46
Structure: L,2
1. <VLAACK>
2. L,m ;m = No. of Invalid parameters.
1. L,3
1. <VIDp> VID with error
2. <LVACKp> reason
3. L,n {n = 0,2}
1. <LIMITID1> 1st limit in error for VID
2. <LIMITACK1> reason
.
.
m. L,3
1. <VIDm> VID with error
2. <LVACKm> reason
3. L,n {n = 0,2}
1. <LIMITID1>
2. <LIMITACK1> reason
Exceptions:
1. A zero length list, m = 0 indicates no invalid variable attributes.
2. A zero-length list, n = 0 indicates no invalid limit values for that VID.
B. Equipment Initiated - Not applicable.

S2F47 Variable Limit Attribute Request (VLAR)
S2F48 Variable Limit Attribute Send (VLAS)
Description: This message allows the host to query the equipment for current variable
limit attributes definitions for the identified variables.
A. Host Initiated
Host to equipment: S2F47
Structure: L,m m = No. of VID’s for this request
1. <VID1>
.
.
m. <VIDm>
Exception: A zero length list m = 0 requests a list of all VID values that can
have variable limit attributes.
