1.01 Module Error Present.
This status bit is set when the DSM314 detects any error. Errors
related to a specific Servo or Auxiliary Axis will be identified in the associated
Axis n Error Code
%AI word. Module errors not related to a specific axis will be identified in the
Module Status
Code
%AI word. See section 2, “%AI Status Words”, for more details. The
Clear Error
%Q bit
is the only command that will clear the
Module Error Present
%I status bit and the associated
Module Status Code
and
Axis n Error Code
%AI word(s). If the condition causing the error is
still present, the
Module Error Present
%I status bit will not be cleared.
1.02 Local Logic Active.
When this status bit is ON, it indicates that a Local Logic program is
executing.
1.03 New Configuration Received
.
The
New Configuration Received
%I status bit is set
whenever the PLC sends a reset command or new configuration to the DSM314.
New
Configuration Received
should be cleared by a PLC program before any %AQ Immediate
commands such as
In Position Zone
or
Position Loop Time Constant
have been sent to the
DSM314. The status bit can then be monitored by the PLC. If the bit is set, then the DSM314
has been reset or reconfigured. The PLC should clear the bit and then re-send all necessary %AQ
commands. The bit is cleared by %AQ Immediate command 49h. Refer to section 4, “%AQ
Immediate Commands,” later in this chapter, for more details about the %AQ immediate
command interfaces.
