Error responses
When the MGP 464 receives a valid SIS command, it executes the command and
sends a response to the host device. If the processor is unable to execute the
command because the command is invalid or contains invalid parameters, it
returns an error response to the host. The error response codes are:
E01 — Invalid input channel number (too large)
E09 — Invalid function number (too large)
E10 — Invalid command
E11 — Invalid preset number
E12 — Invalid output number (applies for addressing windows)
E13 — Invalid value (out of range)
E14 — Invalid for this configuration
E17 — Invalid command for signal type
E24 — Privilege violation
E26 — Maximum number of users connected has been exceeded
E27 — Invalid event number
E28 — Bad filename/File not found
Telnet and Web communications
The MGP 464 can also be controlled via an IP connection using either Telnet
(port 23) or a Web browser (port 80). The ASCII and URL commands listed in the
tables later in this chapter perform the same functions, but are encoded differently
to accommodate the requirements of each port (Telnet or browser).
The ASCII to hexadecimal (hex) character conversion table below is for use with the
Command/response table for SIS commands, beginning on page 4-9.
ASCII to HEX Conversion Table
•
ASCII to hexadecimal character conversion table
The command/response tables list valid ASCII (for Telnet) command codes, the
corresponding URL encoded (for Web browsers) command codes, the processor’s
responses to the host, and a description of the command’s function or results from
executing the command.
• Upper- and lowercase letters may be used interchangeably in the command
field unless otherwise specified.
• Commands may be sent back-to-back without spaces; for example, 2*2!2*0B.
• Numbers can be entered as 1 digit, or as 2 or 3 digits with leading zeros; for
example, 8V = 08V = 008V.
