1. Panel meter K40-232
Display for ASCII protocol with RS-232 bus, in 96 x 48 mm (1/8 DIN) format
Digital panel meter, with ASCII code repeater function, in 96 x 48 mm
size (1/8 DIN) and 4 digits with 20 mm digit height. Reading value,
together with decimal point, are controlled via the RS-232 bus, us -
ing the ASCII protocol described in this document
(see section 1.13)
.
Reading up to 9999 and -1999.
Three working modes available allow to work with numbers or al
-
phanumerical symbols. Alarms can be controlled directly from the
RS-232 bus or locally from the instrument.
• The ‘Process slave’
(see section 1.2) mode works with numerical
values, and alarms are controlled locally.
• The ‘Full slave’
(see section 1.3)
mode works with numerical val -
ues, and alarms are controlled from the bus.
• The ‘Text’
(see section 1.4)
mode works with alphanumerical val -
ues, and alarms are controlled from the bus.
Bus speed configurable up to 38.400 bps and address configurable
from 1 to 31. Accepts a ‘broadcast’ function at address 128. ‘Watch -
dog’ function detects if communication with the master is lost.
‘Watchdog’ function can display a message on display and control
the activation of selected alarms
(see section 1.25)
.
Function ‘bus activity’ is a utility for troubleshooting communica -
tions
(see section 1.26)
. Function ‘On power up’ defines the alarm
state at start-up
(see section 1.28.8)
.
Front protection IP65. Connections by plug-in screw terminals. For
industrial applications.
• ‘
Fast access
’ menu to selected functions, accessible with key UP (
5
)
(see section 1.28.6)
Memory for maximum and minimum reading, password protection,
5 brightness levels.
