6. sorry about the confusion Note that only the contents of 1 register s bits may be read at a time This means that a bit position of 9 2 8 bit will 44 only allow 8 bits to be read This is due to the fact that there are only 16 bits available in one register and we are starting at bit 8 this leaves a result of 8 bits Omitting the bit position parameter will specify that the read will return whole registers rather than bits Refer to the following examples for samples of how to specify bits or whole registers of registers bits is the number of consecutive registers memory locations or bits that you wish to read If the bit position parameter is omitted of registers bits will specify the number of 16 bit registers to read If you wish to read more than one register or memory location at a time this number will be the number of consecutive registers or locations you wish to read If you have included a bit position parameter this number will be the number of consecutive bits you wish to read variable array is the variable name or array name where you wish to store the data you are reading If you are reading only one register or bit you may use any variable type you wish If you are reading multiple registers this variable MUST be a short integer array variable If you are reading registers or memory locations that are stored as words and the of registers bits is greater than one this will be a short integer array make sure y

68. tion is 1 through 16 By specifying this parameter a bit single or multiple write will be performed For example specifying a bit position of 2 will allow the write to place data 45 contained in the variable array bit 0 2 0 bit in the bit 2 2 1 bit position of the result Note that all Eason documentation references bits 0 through 15 for bits inside variables in the EASON while SY MAX documentation references bits through 16 for registers in the PLC sorry about the confusion Note that only the contents of 1 register s bits may be written at a time This means that a bit position of 9 2 8 bit will only allow 8 bits to be written This is due to the fact that there are only 16 bits available in one register and we are starting at bit 8 this leaves a result of 8 bits Omitting the bit position parameter will specify that the write will return whole registers rather than bits Refer to the following examples for samples of how to specify bits or whole registers of registers bits is the number of consecutive registers memory locations or bits that you wish to write If the bit position parameter is omitted of registers bits will specify the number of 16 bit registers to write If you wish to write more than one register or memory location at a time this number will be the number of consecutive registers or locations you wish to write up to a maximum of 16 If you have included a bit position parameter this number will be the n
69. to write more than one register or memory location at a time this number will be the number of consecutive registers or locations you wish to write If you are writing the status of more than one I O bit this number will be the number of consecutive bits you wish to write expression variable array is the expression variable or array data you wish to write to the PLC s I O registers or other memory locations If the value of of registers bits see above is 1 this will be an expression or a variable If the number of words is greater than one this must be an array make sure you properly dimension the array prior to using it If you wish to write the status of up to 16 I O bits you will be writing one word and therefore will need to use an expression or discrete variable name If you wish to set more than 16 consecutive bits you will need to use an array The dimension of the array variable will be the next integer greater than the desired number of bits divided by 16 For example if you wish to set the status of bits 1 24 you will need to dimension your array to at least two since 24 16 1 5 and two is the next greater integer Remember any time you are writing more than one word of data more than one register or more than 16 bits you must use a dimensioned array variable Examples 41 10 CALL PLCWRITE 1 3 9 2 3 This command writes a 1 to outputs 0 and 1 Note that 3 represents the binary 11 which is the bit pattern desir
70. umber of bits to be written always use a for now variable number this is the variable or number that is to be written in memory Examples CALL PLCWRITE 1 3 0 5 1 This command tells the PLC to turn on output 5 Note that the FP address format is Yxxy this translates to a CALL PLCWRITE 1 3 xx y 1 where y is in decimal converted from the hex value CALL PLCWRITE 1 4 40 1 555 This instructs the PLC to write into the data register at address 40 the value of 555 61
71. umber of consecutive bits you wish to write variable array is the variable name or array name where you wish to store the data you are writing If you are writing only one register or bit you may use any variable type you wish If you are writing multiple registers this variable can either be a short integer array variable or a constant like 1234 If you are writing registers or memory locations that are stored as words and the of registers bits is greater than one this will be a short integer array make sure you properly dimension the array prior to using it If you are writing the status of more than one but less than 16 I O bits you will be writing one word and therefore will need to use a single short integer Remember any time you are writing more than one register you must use a dimensioned short integer array Examples 10 CALL PLCWRITE 1 15 1 2 3 This command writes a 1 to register 15 bits 1 and 2 Note that 3 represents the binary 11 which is the bit pattern desired 10 DIM newdat 10 20 CALL PLCWRITE 1 5 2 newdat 4 This command writes the value of newdat 4 to register 5 and newdat 5 to register 6 in a PLC with an id address 1 10 CALL PLCWRITE 1 100 1 1234 Note that you cannot write to multiple locations with the same data ie CALL PLCWRITE 1 100 10 1234 as this will generate a VARIABLE REQUIRED BASIC error This operation must be performed by initializing elements of a dimen
