D.3.1 A5B9 Fast Meter Status
Acknowledge Message
In response to the A5B9 request, the
SIMPRO-100 Relay clears the Fast Meter
(message A5D1) Status Byte. The SIMPRO-100
Relay Status Byte contains one active bit, STSET
(bit 4). The bit is set on power up and on settings
changes. If the STSET bit is set, the external
device should request the A5C1, A5C2, and
A5C3 messages. The external device can then
determine if the scale factors or line configuration
parameters have been modified.
In response to the A5CE request, the relay sends
the block shown in Table D.8.
Table D.8 A5CE Fast Operate Configuration Block
Table 0.1 A 5CE Fast Ope rate Configurati on Block
The SIMPRO-100 Relay performs the specified
remote bit operation if the following conditions are
true:
• The Operate code is valid.
• The Operate validation =
4 • Operate code + 1.
• The message checksum is valid.
• The FASTOP port setting is set to Y.
• The relay is enabled.
Remote bit set and clear operations are latched
by the relay. Remote bit pulse operations assert
the remote bit for one processing interval
(1/4 cycle).
It is common practice to route remote bits to
output contacts to provide remote control of the
relay outputs. If you wish to pulse an output
contact closed for a specific duration, Siemens
recommends using the remote bit pulse
command and control equations to provide
secure and accurate contact control. The remote
device sends the remote bit pulse command; the
relay controls the timing of the output contact
assertion. You can use any remote bit and any
control equation timer to control any of the output
contacts.
