Jumper Selection
A jumper on the carrier can be used to select the output default mode. If no
jumper is installed on pins B13 and B14 outputs hold their last state (the last
commanded value from the backplane) if backplane power or communications
are interrupted or the PLC is stopped. With a jumper installed, if such
conditions occur outputs default to 4mA. This should only be changed with field
power and backplane power removed.
