Communications with Multiple
Controls
CAUTION: Each control connected to either a
direct or modem connection configuration must
have a unique communications address. If two or
more controls share the same address, corrupted
communication will result.
The remote addressing capability of CapTalk
®
S-6280 Communications Software and the M-6280A
Digital Capacitor Bank Control allows multiple
controls to share a direct or network connection. A
fiber optic loop network (see Figure 3‑7, Fiber Optic
Connection Loop), RS‑485 tree configuration (see
Figure 3‑8, RS‑485 Connection Tree) or Ethernet
Network (see Figure 3‑9, Optional Ethernet Network
Connection) may also be used.
A control address of zero is a "wild card" that will
illicit a response from all controls on a shared
connection and result in corrupted communication.
With these arrangements, any control can be
selected from within CapTalk by specifying it’s
unique communications address, ranging from 1
to 200. The communication address must have
previously been set from the control’s front panel.
3.9 Cautions
Control and CapTalk Compatibility
Every attempt has been made to maintain
compatibility with previous control software
versions. In some cases (most notably, with older
controls), compatibility cannot be maintained.
However, CapTalk should work correctly with more
than one version of the M-6280A Series Digital
Capacitor Bank Controls on a single bus, provided
that the controls are all set to use the same protocol.
If there is any question about compatibility, contact
the factory.
Control Priority
Control conflicts will not occur as local commands
initiated from the front panel receive priority
recognition.
Time and Date Stamping
Time and date stamping of events is only as useful
as the validity of the control’s internal clock. Under
the
Configuration/System Clock menu, the Set
Control Date/Time command allows you to manually
set the control’s clock. For reference, the computer’s
clock is also displayed.
