Error Sources and Reasons
This section describes the typical problems and sources of error that come up while
commissioning the ILX69-PBM
Behavior Significance Typical Reason Help
CompactLogix™ I/O LED is
flashing green No communication
with the ILX69-PBM
(or other modules) - ILX69-PBM slot number
in Studio 5000 program
does not match with the
physical slot of the module
- Configured Input / Output
size is wrong - Check ILX69-PBM slot number
in Studio 5000 project
- Compare configured Input /
Output size with required values
ILX69-PBM COM LED is off,
SYS LED flashing irregular
green Configuration missing
or faulty No configuration stored Download a configuration to the
ILX69-PBM with ProSoft fdt
Configuration Manager
ILX69-PBM COM LED is
static green, SYS LED
flashing cyclic fast green Application
is not ready - PLC is not in RUN mode
- PLC application has set
the NRDY bit
- PLC has no I/O
communication with the
ILX69-PBM - Apply PLC into RUN Mode.
- Check that the PLC application
has deleted the NRDY bit.
-
Check PLC’s I/O LED
ILX69-PBM COM LED is
static red, SYS LED static
green At least one slave is
not in data exchange - Master configuration
does not match with
physical bus configuration
- Configured slave is not
connected on PROFIBUS
network or has a problem - Check PROFIBUS
configuration, slave addresses
etc.
- Use ProSoft fdt Configuration
Manager diagnostics to find the
wrong slave
ILX69-PBM COM LED is
static red, SYS LED flashing
cyclic fast green No communication to
any slave - PROFIBUS cable not
connected
- No slaves connected
- PLC is not in RUN mode - PROFIBUS wiring
- Check if slaves are connected
- Check if PROFIBUS
configuration matches with
physical configuration
- Apply PLC into in RUN mode
Slave input data can not be
found in Studio 5000 program Input array mismatch -Configured input size in
Studio 5000 too small
-Configured input address
table in ProSoft fdt
Configuration Manager
does not match with PLC
program -Check if the configured input
size in Studio 5000 covers the
mandatory size of 88 byte status
data and in ProSoft fdt
Configuration Manager
configured PROFIBUS input
array
-Check if configured Input
address table in ProSoft fdt
Configuration Manager matches
with PLC program
