External Output Block - Mitsubishi Electric MELSEC-L Series LD40PD01 User Manual

External output block

Outline
In the fifth section in the hardware logic outline window, eight external output blocks for DC output ("OUT 0" to "OUT 7") and
six external output blocks for differential output ("OUT 0_DIF" to "OUT 5_DIF") are arranged by default.
The result of the operation from the first to the fourth section in the hardware logic is output from the connector for external
devices (OUT 0 to OUT 7, OUT 0_DIF to OUT 5_DIF).
The external output block has the following functions.
• When "Logic Select" is set to "Inversion", inverted signals are output.
• A delay between signals caused by different external interface circuits can be adjusted by setting a delay time.
• When an error occurs in the CPU module, signals are output according to the output setting specified with "Error-time
Output Mode".
