Loop display selection via process–related name (character string) AT,characterstring; (up to 16 characters) A process–related name can be assigned, by parameterization in the block list, to each block with a loop display. If, for example, the name “PRC 1080” is to be assigned to controller 1, the following instruction must be used while the block list is displayed Test instruction: changing the code bit in the output MB,outputno,bitno,value; Test instruction: changing the code bit in the input MB,inputno:E,bitno,value; If the configuration display has been selected, these instructions can be used for setting and resetting code bits in variables for test purposes (exception: types I, ID, S, S2, S4, S16).
Definition of a block
The block name may consist of up to four alphanumerical characters. Special characters and symbols are not permitted (documentation uploading). The largest variable number must be specified in addition when defining the data blocks GA, GB, GM, GT, FA, FSA, FB and FC. D,type,bname:largest vno; A number between 0 and 255 may be entered as largest variable number (so that up to 256 data elements can be created). If no variable number is specified, the data block is created with two data elements. Up to 16 data elements are possible for the FC block.
Although FC blocks can be preset by standard
operations during parameterization, only the keyboard symbols can be entered here. If other symbols, such as the graphic monitor symbols, are to be specified, the following instructions should be used:Index of the first character to be entered in the FC block. dec1 ... decn: Decimal equivalent of the character to be entered. Several consecutive characters can be specified by their decimal equivalents. Symbols of characters are entered in the field .FC; the associated decimal equivalents in the field .FCI.
