Galil DMC-1700, DMC-1800 user manual Connector Description, OP 7,,,,7, J6 50-PINIDC, MG @IN17

Argument	Blocks	Bits	Description
m	0	1-8	General Outputs
a	2,3	17-32	Extended I/O
b	4,5	33-48	Extended I/O
c	6,7	49-64	Extended I/O
d	8,9	65-80	Extended I/O

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).

Configuring the 64 Extended I/O of the DMC-1750 to 1780 and 1850 to 1880 using the DB-14064

The 5 to 8 axis versions of the DMC-1700/1800 are equipped with 24 inputs and 16 outputs (an increase from 8 inputs and 8 outputs on 1 to 4 axis models). Since the numbering system for accessing the extended I/O ranges from 17 to 80, there will be an overlap of inputs from 17 to 24. When configuring the I/O, note that the first bank of extended I/O (17-24) will only be accessible as outputs. Configuring the first block (17-24) as inputs renders them as “no connection” inputs, since these inputs are already accessible through the general I/O on the main board.

The procedure for configuring and accessing the extended I/O on the 5-8 axis versions is then similarly done as described in the previous section. Except, when using the OP command, the argument “m” is a decimal number from 0 to 65535, which refers to the first 16 general I/O.

Connector Description:

The DMC-17x8 controller (and DB-14064) has two 50 Pin IDC header connectors. The 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.
