Acquire data from the gateway(s)
Data, in the form of 16-bit status words, can be acquired from up to four
gateways that are connected to the OIS. To speed up operation, the OIS
should be configured to look at only the tables of interest. The two areas
most likely to be of interest are those containing the process variable and
the device status. See the section on Datatables.
Process variable word A 16-bit word that represents the ana-
log signal of a device.
Status word A 16-bit word that provides 16 pieces
of discrete status information for a sin-
gle point. See the section on Point
Configuration.
Acquire data from a programmable device
EagleVision can acquire the contents of Modbus memory registers,
0xxxx, 1xxxx, 3xxxx, 4xxxx, from a programmable device.
Write data to a programmable device
EagleVision can write data to the Modbus memory registers, 0xxxx,
1xxxx, 3xxxx, 4xxxx, of a programmable device.
Write data to the gateway(s)
EagleVision can write (set) individual “bits” or whole “words” to any
gateway or other Modbus RTU slave device that is connected to the OIS.
This can initiate sequences (commands) or set analog setpoints, timer pre-
sets, etc., within the gateway.
Event logging
Changes in the data being monitored by EagleVision from any of its
attached slave devices (Eagle gateways, PLC’s, etc.) can be used to trig-
ger an “event.” Up to 5000 of these “events” can be configured for mon-
itoring. An event can be logged to any or all of the following places:
■ The three line event window at the bottom of the OIS screen
■ The daily event log file (stored on the hard drive)
■ The printer (printed in a variety of color formats).
Graphic displays
The EagleVision program allows any Macintosh application that uses
external commands (XCMD’s) and external functions (XFCN’s) to commu-
nicate with any gateway or programmable device connected to the OIS.
This allows creation of custom graphic screens to display system status.
Sample SuperCard and HyperCard stacks are included, which contain
the XCMD and XFCN library. To use the XCMD’s and XFCN’s with anoth-
er program, contact Det-Tronics.
