Module Pin Connections - ABB Symphony Harmony Series Instruction

Module Pin Connections

calibrate the analog input zero offset and gain are not within
tolerance or the analog inputs are not within tolerance.
1. Check the analog inputs to verify that their voltages are
within specifications (1 to 5 VDC).
2. Check the analog inputs to verify that their common mode
voltage is within specifications (±10 VDC).
If the analog inputs are correct, replace the I/O module.
The address set on address switch (S1) and in the controller
Missing slave
configuration must be the same. The controller generates a
module error
MISSING SLAVE MODULE ERROR if they do not match. Verify
that the address set on switch S1 is the same as the address in
FC 79, specification S1. If not:
1. Remove the module and change the setting of switch S1 to
correspond with the controller configuration (refer to the
in Section 3 for the procedures
Address Selection Switch (S1) Address Selection Switch (S1) Address Selection Switch (S1) Address Selection Switch (S1)
to set an address and to install an I/O module).
2. Modify the address in the controller configuration (FC 79,
specification S1) to correspond with the address set on switch
S1. Use the human system interface to modify the configura-
tion (for procedures on how to modify a function code specifi-
cation, refer to the appropriate instruction manual for the
human system interface you are using).
The controller generates a missing slave module error if the
I/O expander bus is not connected to the I/O module. Verify
the bus connection on the module mounting unit backplane.
If the I/O module is faulty, replace it with a new one. Refer to
Section 7 for procedures to replace an I/O module.
Module Pin Connections
The I/O module has three connection points for external sig-
nals and power (P1, P2 and P3). Tables 5-2, 5-3 and 5-4 show
the pin connections.
