4 HOW TO READ INSTRUCTIONS
*1 For the description for the individual devices, refer to the User's Manual (Function Explanation, Program Fundamentals) for the CPU
module used.
*2 FX and FY can be used only for bit data, and FD only for word data.
*3 When T, ST, and C are used for other than the instructions below, only word data can be used. (Bit data cannot be used.)
[Instructions that can be used with bit data]
LD, LDI, AND, ANI, OR, ORI, LDP, LDF, ANDP, ANDF, ORP, ORF, LDPI, LDFI, ANDPI, ANDFI, ORPI, ORFI, OUT, RST, BKRST
*4 Usable with CC-Link IE Controller Network, CC-Link IE Field Network, MELSECNET/H, and MELSECNET/10.
*5 The "Constant" and "Other" columns describe the devices which can be set.
Indicates ladder mode expressions and execution conditions for instructions.
Execution condition Non-conditional
