Precautions Do not read or write the system word (C) from any other instruction.
MTR(213) will not operate correctly if the system word is accessed by another
instruction. The system word is not initialized by MTR(213) in the first cycle
when program execution starts. If MTR(213) is being used from the first cycle,
clear the system word from the program.
MTR(213) will not operate correctly if I/O refreshing is not performed with the
Input Unit and Output Unit connected to the external matrix after MTR(213) is
executed. Consequently, set the input time constant for the Input Units used
for the data line input word to a value that is shorter than the cycle time, or do
not connect the external matrix to the following Units.
• Basic I/O Units or High-density I/O Units mounted in a SYSMAC BUS
Remote I/O Slave Rack
• Communications Slaves (DeviceNet or CompoBus/S Slaves)
Example In this example, MTR(213) reads the 64 bits of data from the 8
×
8 matrix and
stores the data in W000 to W003. The 8
×
8 matrix is connected through
CIO 0100 (allocated to a CS1W-ID211 16-point DC Input Unit) and CIO 0200
(allocated to a CS1W-OD211 16-point Transistor Output Unit). D32000 is
used as the system word.
3-23-9 7-SEGMENT DISPLAY OUTPUT – 7SEG(214)
Purpose Converts the source data (either 4-digit or 8-digit BCD) to 7-segment display
data, and outputs that data to the specified output word.
This instruction is supported only by CS/CJ-series CPU Unit Ver. 2.0 or later.
