In mnemonic code, the execution condition is stored at the branching pointusing the TR bit as the operand of the OUTPUT instruction. This execution con-dition is then restored after executing the right-hand instru...

105 When drawing a ladder diagram, be careful not to use TR bits unless necessary.Often the number of instructions required for a program can be reduced andease of understanding a program increased by redrawing a diagram that wouldotherwise required TR bits. In both of the following pairs of diagram...

107 If IR 00000 in the above diagram is OFF (i.e., if the execution condition for thefirst INTERLOCK instruction is OFF), instructions 1 through 4 would be ex-ecuted with OFF execution conditions and execution would move to the instruc-tion following the INTERLOCK CLEAR instruction. If IR 00000 is O...

108 The other type of jump is created with a jump number of 00. As many jumps asdesired can be created using jump number 00 and JUMP instructions using 00can be used consecutively without a JUMP END using 00 between them. It iseven possible for all JUMP 00 instructions to move program execution to t...

109 4-8-1 DIFFERENTIATE UP and DIFFERENTIATE DOWN DIFFERENTIATE UP and DIFFERENTIATE DOWN instructions are used toturn the operand bit ON for one cycle at a time. The DIFFERENTIATE UP in-struction turns ON the operand bit for one cycle after the execution condition forit goes from OFF to ON; the DIF...

110 To create a self-maintaining bit, the operand bit of an OUTPUT instruction isused as a condition for the same OUTPUT instruction in an OR setup so that theoperand bit of the OUTPUT instruction will remain ON or OFF until changes oc-cur in other bits. At least one other condition is used just bef...

111 Work bits can be used to simplify programming when a certain combination ofconditions is repeatedly used in combination with other conditions. In the follow-ing example, IR 00000, IR 00001, IR 00002, and IR 00003 are combined in alogic block that stores the resulting execution condition as the s...

112 This action is easily programmed by using IR 22500 as a work bit as the operandof the DIFFERENTIATE UP instruction (DIFU(13)). When IR 00000 turns ON, IR22500 will be turned ON for one cycle and then be turned OFF the next cycle byDIFU(13). Assuming the other conditions controlling IR 00100 are ...

113 Except for instructions for which conditions are not allowed (e.g., INTERLOCKCLEAR and JUMP END, see below), every instruction line must also have atleast one condition on it to determine the execution condition for the instructionat the right. Again, diagram A , below, must be drawn as diagram ...

114 4-11 Program Execution When program execution is started, the CPU cycles the program from top to bot-tom, checking all conditions and executing all instructions accordingly as itmoves down the bus bar. It is important that instructions be placed in the properorder so that, for example, the desir...

118 5-1 Notation In the remainder of this manual, all instructions will be referred to by their mne-monics. For example, the Output instruction will be called OUT; the AND Loadinstruction, AND LD. If you’re not sure of the instruction a mnemonic is used for,refer to Appendix B Programming Instructio...

! 119 Caution The IR and SR areas are considered as separate data areas. If an operand has access to onearea, it doesn’t necessarily mean that the same operand will have access to the other area. Theborder between the IR and SR areas can, however, be crossed for a single operand, i.e., the lastbit i...

! 120 A non-differentiated instruction is executed each time it is cycled as long as itsexecution condition is ON. A differentiated instruction is executed only once af-ter its execution condition goes from OFF to ON. If the execution condition hasnot changed or has changed from ON to OFF since the ...

122 5-6 Coding Right-hand Instructions Writing mnemonic code for ladder instructions is described in Section 4 Writing and Inputting the Program. Converting the information in the ladder diagramsymbol for all other instructions follows the same pattern, as described below,and is not specified for ea...

124 Multiple Instruction Lines If a right-hand instruction requires multiple instruction lines (such as KEEP(11)),all of the lines for the instruction are entered before the right-hand instruction.Each of the lines for the instruction is coded, starting with LD or LD NOT, to form‘logic blocks’ that ...

Instruction Set Lists Section 5-7 125 5-7 Instruction Set Lists This section provides tables of the instructions available in the C200HS. The firsttable can be used to find instructions by function code. The second table can beused to find instruction by mnemonic. In both tables, the @ symbol indica...

132 Precautions DIFU(13) and DIFD(14) operation can be uncertain when the instructions areprogrammed between IL and ILC, between JMP and JME, or in subroutines. Re-fer to 5-10 INTERLOCK and INTERLOCK CLEAR – IL(02) and ILC(03), 5-11 JUMP and JUMP END – JMP(04) and JME(05), and 5-23 Subroutines and I...

134 Description KEEP(11) is used to maintain the status of the designated bit based on two exe-cution conditions. These execution conditions are labeled S and R. S is the setinput; R, the reset input. KEEP(11) operates like a latching relay that is set by Sand reset by R. When S turns ON, the design...

135 Example If a HR bit or an AR bit is used, bit status will be retained even during a powerinterruption. KEEP(11) can thus be used to program bits that will maintain statusafter restarting the PC following a power interruption. An example of this that canbe used to produce a warning display follow...

137 Example The following diagram shows IL(02) being used twice with one ILC(03). 00000 00001 ILC(03) IL(02) 00004 00005 00003 00002 IL(02) 00502 TIM 511 CP R CNT 001 IR 010 00100 001.5 s TIM 511 #0015 Address Instruction Operands 00000 LD 00000 00001 IL(02) 00002 LD 00001 00003 TIM 511 # 0015 00004...

138 If the jump number for JMP(04) is 00, the CPU will look for the next JME(05) witha jump number of 00. To do so, it must search through the program, causing alonger cycle time (when the execution condition is OFF) than for other jumps.The status of timers, counters, bits used in OUT, bits used in...

139 Any one TC number cannot be defined twice, i.e., once it has been used as thedefiner in any of the timer or counter instructions, it cannot be used again. Oncedefined, TC numbers can be used as many times as required as operands ininstructions other than timer and counter instructions. TC number...

140 If the execution condition remains ON long enough for TIM to time down to zero,the Completion Flag for the TC number used will turn ON and will remain ONuntil TIM is reset (i.e., until its execution condition is goes OFF). The following figure illustrates the relationship between the execution c...

142 The length of time that a bit is kept ON or OFF can be controlled by combiningTIM with OUT or OUT NO. The following diagram demonstrates how this is pos-sible. In this example, 00204 would remain ON for 1.5 seconds after 00000 goesON regardless of the time 00000 stays ON. This is achieved by usi...

150 5-15 Data Shifting All of the instructions described in this section are used to shift data, but in differ-ing amounts and directions. The first shift instruction, SFT(10), shifts an execu-tion condition into a shift register; the rest of the instructions shift data that is al-ready in memory. 5...

153 Description SFTR(84) is used to create a single- or multiple-word shift register that can shiftdata to either the right or the left. To create a single-word register, designate thesame word for St and E. The control word provides the shift direction, the statusto be put into the register, the sh...
