The command, OP, may also be used to set output bits, specified as blocks of data. The OP command accepts 5 parameters. The first parameter sets the values of the main output port of the controller (Outputs 1-8, block 0). The additional parameters set the value of the extended I/O as outlined:

OP m,a,b,c,d

where m is the decimal representation of the bits 1-8 (values from 0 to 255) and a,b,c,d represent the extended I/O in consecutive groups of 16 bits. (values from 0 to 65535). Arguments which are given for I/O points which are configured as inputs will be ignored. The following table describes the arguments used to set the state of outputs.

For example, if block 8 is configured as an output, the following command may be issued: OP 7,,,,7

This command will set bits 1,2,3 (block 0) and bits 65,66,67 (block 8) to 1. Bits 4 through 8 and bits 68 through 80 will be set to 0. All other bits are unaffected.

When accessing I/O blocks configured as inputs, use the TIn command. The argument 'n' refers to the block to be read (n=0,2,3,4,5,6,7,8 or 9). The value returned will be a decimal representation of the corresponding bits.

Individual bits can be queried using the @IN[n] function (where n=1 through 8 or 17 through 80). If the following command is issued;

MG @IN[17]

the controller will return the state of the least significant bit of block 2 (assuming block 2 is configured as an input).

Connector Description:

The DMC-13X8 controller has a single 80-pin high density connector for the extended I/O. This cable may then be connected to either the IOM-1964 directly, or to two 50 Pin IDC header connectors on the CB-50-80. The 50-pin IDC connectors are compatible with I/O mounting racks such as Grayhill 70GRCM32-HL and OPTO-22 G4PB24.

Note for interfacing to OPTO-22 G4PB24: When using the OPTO-22 G4PB24 I/O mounting rack, the user will only have access to 48 of the 64 I/O points available on the controller. Block 5 and Block 9 must be configured as inputs and will be grounded by the I/O rack.
