Processor Error Responses
When the USP 507 receives an SIS command and determines that it is valid, it
performs the command and sends a response to the host device. If the processor
is unable to perform the command because the command is invalid or contains
invalid parameters, the processor returns an error response to the host. The error
response codes are:
E01 — Invalid input channel number (out of range)
E10 — Invalid command
E11 — Invalid preset number
E12 — Invalid output number/port number
E13 — Invalid parameter (out of range)
E14 — Command not available for this configuration
E17 — Invalid command for this signal type
E22 — Busy
E24 — Privilege violation
E25 — Device not present
E26 — Maximum number of connections exceeded
E27 — Invalid event number
E28 — Bad filename/file not found
Using the Command/Response Table for SIS Commands
The command/response table begins on page 4-7. Lowercase letters are acceptable
in the command field except where indicated. The table below shows the
hexadecimal equivalent of ASCII characters used in the command/response tables.
