MTR(213) outputs the selection signals to bits 00 to 07 of O, reads the data in order from bits 00 to 07

of I, and stores the 64 bits of data in the 4 words D through D+3. MTR(213) reads the status of the 64-

bit matrix every 24 CPU Unit cycles. The One Round Flag (bit 08 of O) is turned ON for one cycle in

every 24 cycles after each of the selection signals has been turned ON.

External Connections

Connect the hexadecimal keypad to Input Unit contacts 0 to 7 and Output Unit contacts 0 to 7, as

shown in the following diagram.

The inputs and outputs can be connected to the following kinds of Basic I/O Units and High-density I/O

Units as long as they are not mounted in a SYSMAC BUS Remote I/O Rack.

• DC Input Units with 8 or more input points

• Transistor Output Units with 8 or more output points
