Description
Opto-isolated industrial auxiliary signal 0 (output).
Supported output: user-bit 0 (M_USER_BIT0), timer output (M_TIMERn),
a I/O command register bit (M_IO_COMMAND_LISTn +M_IO_COMMAND_BITn).
Opto-isolated industrial auxiliary signal 1 (output).
Supported output: user-bit 1 (M_USER_BIT1), timer output (M_TIMERn),
a I/O command register bit (M_IO_COMMAND_LISTn +M_IO_COMMAND_BITn).
External voltage source used by the on-board pullup circuitry (when instantiated)
of auxiliary signals 0 to 3 (output) and auxiliary signals 8 to 11 (input).
Opto-isolated industrial auxiliary signal 2 (output).
Supported output: user-bit 2 (M_USER_BIT2), timer output (M_TIMERn),
a I/O command register bit (M_IO_COMMAND_LISTn +M_IO_COMMAND_BITn).
Opto-isolated industrial auxiliary signal 3 (output).
Supported output: user-bit 3 (M_USER_BIT3), timer output (M_TIMERn),
a I/O command register bit (M_IO_COMMAND_LISTn +M_IO_COMMAND_BITn).
TTL output common return path.
