Polled I/O Configurations
SJ100DN inverters offer three host output and host input polled I/O data configurations.
These correspond to P_46 / P_47 = 20 / 70, 21 / 71, or 100 / 101. Each configuration
differs in its use of up to 4 output or 4 input words (other combinations can cause
network errors.) The DeviceNet networking example in the previous steps used the
default polled I/O configuration (P_46 = 100 and P_47 = 101). This section describes
each available polled I/O configuration.
Host Output Instance Configurations
– The tables below list the three configurations
for host output data (settable by P_46).
