Error Example
Function code 215 for the slave and 216 for the active channel
need the same address. Check that the address on IMASI03
switch SW1, the address in function code 215 specification 1
and function code 216 specification 1 are the same.
If function code 216 slave address is not the same as function
code 215 the MFP will go into error mode when put into exe-
cute mode. The error will indicate 5, (byte 3 of module sta-
tus/error message = 05) Configuration Error - Undefined
Input.
Modify the address in function code 215 and the associated
216 blocks. The IMASI03 address value set in function code
215 specification 1 and function code 216 specification 1
should match the slave address set on SW1 on the IMASI03
module.
Use an INFI 90 operator interface to change the configuration
data. For procedures on how to change a function code specifi-
cation, refer to the product instruction manual for the operator
interface being used.
The master module generates a local I/O error in the module
status if the slave expander bus is not connected between the
slave module and the master module. Verify that the bus is
connected on the MMU backplane.
NOTE: Setting FC 215 specification 4 to 0 will cause the master
module to
trip when the IMASI03 module fails. Changing specifica-
tion 4 to a 1 causes the master module to
continue to operate if the
IMASI03 fails or is missing.
If both the 215 and 216 blocks have the wrong address, the
MFP status will indicate a local I/O error. To correct this:
Remove the slave module and change the setting of SW1 on
the IMASI03 to match the module configuration settings.
Refer to
for information on setting an address
and installing a slave module.
MODULE FUNCTIONAL TESTS
There are two sections in the slave functional test. Self-con-
tained, dipswitch configurable diagnostics. Slave expander bus
interface testing (requires an MFP).
Test Equipment Requirements
To perform the functional testing, a single powered MMU slot
(+5 V,
±
15 V, and power fail interrupt - PFI) is required. Slave
