Figure 4-5. A sample screen display of the diagnostic software program
For example, assume that data characters 39 and 40 are
ASCII “C” and “8,” respectively. ASCII “C” is 12 in decimal or
1100 in binary. ASCII “8” is 8 decimal or 1000 in binary. This
means that the diagnostic byte for data packets 39 and 40 is
11001000. From this information, Figure 4-7 tells us that:
Channel 1 is ON.
Channel 1 is Clear.
Channel 1 is not weak.
Noise is not detected on Channel 1.
Channel 2 is ON.
Channel 2 is Blocked.
Channel 2 is not weak.
Noise is not detected on Channel 2.
4.6 Remote Interface
The remote interface (terminals 28-31) provides for remote
monitoring of the system status via the optional remote display
(see Section 2.3 Accessories) or via a computer, PLC/PES or
other monitoring device.
The optional remote display provides the same status infor-
mation as the controller status indicators (see Section 4.4).
A diagnostic software program is available on the PICO-
GUARD CD to use with PC-compatible computers for easy
viewing of System status and/or diagnosis of System errors
(see Figure 4-5). The CD opens with an Autorun screen
that contains an installation read-me file, followed by the
installation of the software.
The RS-232 output of the remote interface provides
continuously streaming, ASCII encoded hexadecimal data.
Data packets include 48 ASCII characters (46 data characters
followed by a carriage return and line feed). See Figure 4-6.
The RS-232 output data protocol is:
• 4800 baud rate
• 8 data bits
}
• No parity 8-N-1
• 1 stop bit
• No flow control
When the isolated RS-232 output (terminals 30 and 31) is
connected to a computer, PES or other monitoring device,
the status and diagnostic information shown in Figure 4-7 is
available. Two data packet characters are used to decode each
diagnostic data byte.
