Koyo Driver Addressing

The current Koyo addressing formats work only for the DL series of PLCs.

The input / output tags addressed under the Koyo driver use the addressing system shown here. The simple format of prefacing the address with the register or bit type to be used is utilized. The limits on any actual addresses will depend on the configuration of the system and type of CPU used. Note that bits can be extracted for word addresses by adding a "/" separator followed by the bit number. For example:

R100/0 will read bit zero of the 8 bit data register R100.

Address Type	Data Type
X	Discrete Inputs
Y	Discrete Outputs
R	8 Bit Data Registers
CT	Counter Status Bits
T	Timer Status Bits
CTR or CNT	Counter Accumulated Values
TMR	Timer Accumulated Values
SEQ	Sequencers
SR	Shift Registers
ST or S	Stages
V	Variable Memory
GX	Global Inputs
SP	Special Relays
SC	Scratchpad
D	Diagnostics

Some typical addresses would use the address types listed above followed by the register or bit number. Such as:

X10, Y20, TMR100 or V4010
