1 Phase mode: This field contains the average of the
phase A and B currents (in amps).
byte16, byte17 This field contains the AC frequency (in tenths of hertz).
16.6. MEC 20 Display Details
The Display details are broken into 2 groups. Group 0 contains the 16 ASCII characters
from the top line of the MEC 20 display. Group 1 contains the 16 ASCII characters from
the bottom line of the display. There are to many individual display messages to list all of
them here, however some basic messages should be described. The 2 most useful
messages are "non-valid" and "valid". This is mainly used for confirmation that a
keystroke has been sent and received by the MEC 20 correctly.
Group 0
Field Description
byte0 to byte15
This field contains the ASCII characters from the LCD
top line.
Group 1
Field Description
byte0 to byte15
This field contains the ASCII characters from the LCD
bottom line.
16.7. MEC 20 Fault Details
DigFault 1 - 12 are user programmable (see the table MEC 20 Get Summary , bytes 6 to
9 for fault descriptions), the fault name register can be read or written to any value up to
16 characters long. This must be done locally on the MEC 20's.
Fault Detail Registers are described in more detail below:
Fault Status
Shutdown/Alarm
Description
byte0, byte1
This field contains the fault details bitmap, as follows:
The bits contain TRUE if the fault is programmed as a
shutdown, and FALSE if the fault is programmed as
an alarm.
Byte 0 contains information for digital Faults 0 - 15
(Bit15 =#15, Bit0 = #0)
Byte 1 contains information for digital Faults 16 - 28
(Bit12 =#28, Bit0 =#16)
The message format for all faults is shown below:
