Note that the field interface to the carrier board provided
through connector P2 (refer to Table 21) is NON-ISOLATED.
This means that the field signal return and logic common have a
direct electrical connection to each other. As such, care must be
taken to avoid ground loops (see Section 2 for connection
recommendations) Ignoring this effect may cause operation
errors, and with extreme abuse, possible circuit damage. Refer
to Drawing 4501-550 for example communication wiring and
grounding connections.
LOGIC/POWER INTERFACE
The logic interface to the carrier board is made through
connector P1 (refer to Table 22)P1 also pr5V and
±
12V
to power the module. Not all of the IP logic P1 pin functions are
used.
A programmable logic device installed on the IP Module
provides the control signals required to operate the board. It
decodes the selected addresses in the I/O and ID spaces and
produces the chip selects, control signals, and timing required by
the communication registers and ID PROM, as well as, the
acknowledgment signal required by the carrier board per the IP
specification also prioritizes the interrupts coming in from the
ports.
The ID PROM (read only) implemented on the IP module
provides the identification for the individual module per the IP
specification. The ID PROM, configuration control registers, and
FIFO buffers are all accessed through an 8-bit data bus interface
to the carrier board
5.0 SERVICE AND REPAIR
SERVICE AND REPAIR ASSISTANCE
Surface-Mounted Technology (SMT) boards are generally
difficult to repair. It is highly recommended that a non-functioning
board be returned to Acromag for repair. The board can be easily
damaged unless special SMT repair and service tools are used.
Further, Acromag has automated test equipment that thoroughly
checks the performance of each board. When a board is first
produced and when any repair is made, it is tested, placed in a
burn-in room at elevated temperature, and retested before
shipment
Please refer to Acromag's Service Policy Bulletin or contact
Acromag for complete details on how to obtain parts and repair
PRELIMINARY SERVICE PROCEDURE
Before beginning repair, be sure that all of the procedures in
Section 2, Preparation For Use, have been followed. Also, refer
to the documentation of your carrier board to verify that it is
correctly configured. Replacement of the module with one that is
known to work correctly is a good technique to isolate a faulty
module
CAUTION:POWER MUST BE TURNED OFF BEFORE
REMOVING OR INSERTING BOARDS
Acromag’s Application Engineers can provide further
technical assistance if required. When needed, complete repair
services are also available from Acromag.
