For compatibility with older Host implementations, the Equipment allows the following
alternative form for this message using an array format:
S1F4 W * H->E
<U4 VID...>.
4.3.5 S1F4 - Selected Status Data
S1F4 W * H<-E
<L
<V> * Status Variable Value
...
> .
The Equipment returns the Variable Values in the order requested by S1F3. If any VID
specified in S1F3 is invalid, the corresponding V in S1F4 has the following error format:
<L> * V for Invalid VID
4.3.6 S1F11 - Status Variable Namelist Request
S1F11 W * H->E
<L
<U4 VID> * Status Variable ID
...
>.
The Host format descriptions for the specified Variables. Several VIDs can be specified if
desired.
Normally, only VIDs of class SV (i.e. Status Variables) are used in this message.
However, any VID of class DV, EC, or SV can be used.
If S1F11 contains a zero-length list, then the Equipment will report all variables of class
SV, in order by VID.
S1F11 W * H->E
<L> .

4.3.7 S1F12 - Status Variable Namelist Reply
S1F12 * H<-E
<L
<L [3]
<U4 VID> * Variable ID
<A SVNAME> * Status Variable Name
<A UNITS> * Units of Measure
...
> .
The Equipment returns the Variable descriptions in order requested in S1F11. If any VID
specified in S1F11 is invalid, the corresponding List in S1F12 has the following error
format:
<L> * Instead of L [3]
4.3.8 S1F13 - Connect Request
The Equipment sends this message using the following format.
S1F13 W * H<-E
<L
<A MDLN>
<A SOFTREV>
> .
The Host sends this message using the following format.
S1F13 W * H->E
<L> .
Either end of the link may send S1F13 as the first message to establish connection of the
link.
Under the SIPLACE's initialization logic, the Equipment will always attempt to establish
the link. If no Host acceptance reply is received, the Equipment sends this message
periodically.

4.3.9 S1F14 - Connect Request Acknowledge
The Equipment sends this message using the following format:
S1F14 * H<-E
<L
<B [1] 00> * COMMACK
<L
<A MDLN>
<A SOFTREV>
>
> .
The Host sends this message using the following format:
S1F14 * H->E
<L
<B [1] 00> * COMMACK
<L>
> .
The Equipment always sends the value 0x00 for COMMACK.
In messages received from the Host, COMMACK value 0x00 indicates acceptance of the
connect request. Any other value indicates refusal.
4.3.10 S1F15 - Request Off-Line
S1F15 W . * H -> E
Host requests the Equipment to go Off-Line.
4.3.11 S1F16 - Off-Line Acknowledge
S1F16 * H <- E
<B [1] 0x00> . * OFLACK
Equipment Control State transits to Host Off-Line and sends this message in response to
S1F15 primary. OFLACK is always zero.
4.3.12 S1F17 - Request On-Line
S1F17 W . * H -> E
Host requests the Equipment to go On-Line.
4.3.13 S1F18 - On-Line Acknowledge
S1F18 * H <- E
<B [1] ONLACK> .
