If, for example, 18 isspecified as the beginning word for writing, and three words of data are specified, then 20 will become the last word for writing data, and the command will notbe executed because HR 20 is beyond area boundary.259SectionHost Link Commands4-54-5-11 PV WRITE – WCWrites the PVs (present values) of timers/counters starting from the specifiedtimer/counter.Command Format@x 101 x 100Node no.Wx 103 x 102 x 101 x 100 x 103 x 102 x 101 x 100CHeadercodeBeginning timer/counter*Write data (1 timer/counter)↵TerminatorFCSWrite data(for no.

When this command is used to write data to the PV area, the CompletionFlags for the timers/counters that are written will be turned OFF.2.
If data is specified for writing which exceeds the allowable range, an errorwill be generated and the writing operation will not be executed. If, for example, 126 is specified as the beginning word for writing in a CPM1 PC, andthree words of data are specified, then 128 will become the last word for writing data, and the command will not be executed because TC 128 is beyondarea boundary.4-5-12 TC STATUS WRITE – WGWrites the status of the Completion Flags for timers and counters in the TC area,starting from the specified timer/counter (number).

If, for example, 126 isspecified as the beginning word for writing in a CPM1 PC, and three words ofdata are specified, then 128 will become the last word for writing data, and thecommand will not be executed because TC 128 is beyond area boundary.4-5-13 DM AREA WRITE – WDWrites data to the DM area, starting from the specified word.

If an attemptis made to write to any of these words, the writing operation will not be executedfor these words and the command will end normally.ParametersWrite Data (Command)Specify in order the contents of the number of words to be written to the DM areain hexadecimal, starting with the specified beginning word.Note1. If data is specified for writing which exceeds the allowable range, an errorwill be generated and the writing operation will not be executed.
If, for example, 1022 is specified as the beginning word for writing in a CPM1 PC, andthree words of data are specified, then 1024 will become the last word forwriting data, and the command will not be executed because DM 1024 isbeyond the writable range.2. Be careful about the configuration of the DM area, as it varies depending onthe CPU Unit model.261SectionHost Link Commands4-54-5-14 AR AREA WRITE – WJWrites data to the AR area, starting from the specified word.

If, for example, 12 isspecified as the beginning word for writing in a CPM1 PC, and five words of dataare specified, then 16 will become the last word for writing data, and the command will not be executed because AR 16 is beyond the writable range.4-5-15 SV READ 1 – R#Searches for the first instance of a timer or counter instruction (TIM, TIMH(15),TIML(––), TMHH(––), CNT, or CNTR(12)) with the specified TC number in theuser’s program and reads the PV, which is assumed to be set as a constant. TheSV that is read is a 4-digit decimal number (BCD). The program is searched fromthe beginning, which may take as much as 10 seconds to produce a response.Command Format@x 101 x 100Node no.R#OP1 OP2 OP3 OP4 x 103 x 102 x 101 x 100HeadercodeNameTC number*↵TerminatorFCSNote TC number: 0000 to 0255 in CPM2A/CPM2C PCs and 0000 to 0127 inCPM1/CPM1A/SRM1(-V2) PCsResponse Format@x 101 x 100Node no.262R#Headercodex 161 x 160 x 103 x 102 x 101 x 100End codeSVFCS↵TerminatorSectionHost Link CommandsParameters4-5Name, TC Number (Command)Specify the instruction for reading the SV in “Name.” Make this setting in 4 characters.

The instruction specified under “Name” must be in four characters.2. If the same instruction is used more than once in a program, only the first onewill be read.3. Use this command only when it is definite that a constant SV has been set.4. The response end code will indicate an error (16) if the SV wasn’t entered asa constant.4-5-16 SV READ 2 – R$Reads the constant SV or the word address where the SV is stored.
The SV thatis read is a 4-digit decimal number (BCD) written as the second operand for theTIM, TIMH(15), TIML(––), TMHH(––), CNT, or CNTR(12) instruction at the specified program address in the user’s program. This can only be done with a program of less than 10K.Command Format@x 101 x 100Node no.R$x 103 x 102 x 101 x 100 OP1 OP2 OP3 OP4 x 103 x 102 x 101 x 100HeadercodeProgramaddressNameTC number*FCS↵TerminatorNote TC number: 0000 to 0255 in CPM2A/CPM2C PCs and 0000 to 0127 inCPM1/CPM1A/SRM1(-V2) PCsResponse Format@x 101 x 100Node no.An end code of 00 indicates normal completion.R$Headercodex 161 x 160 OP1 OP2 OP3 OP4 x 103 x 102 x 101 x 100End codeOperandSVFCS↵Terminator263SectionHost Link CommandsParameters4-5Name, TC Number (Command)Specify the name of the instruction for reading the SV in “Name.” Make this setting in 4 characters.
