2 1 Th Drct Accss (Programlss) format, whch dos not burdn th PLC wth protocol programs, runs communcaton btwn th GP and PLC. Ths chaptr dscrbs. 1.1 Communcaton Mthod Dpndng on th part or tag stup, th GP can asly spcfy th PLC dvc. By dong so, th GP automatcally rqusts th data rqurd for opratons (Systm Data) and th scrn dsplay from th PLC. Thn th GP, dpndng on th PLC rspons, changs ts scrn dsplay corrspondng to ts anmaton sttngs. Plus, data can b snt to th PLC usng GP touch ky nput. Wth Drct Accss communcaton, th GP s always th mastr n th communcaton lnk. In, data rqurd by th scrn dsplay s automatcally snt and rcvd from th GP. Thrfor, a PLC program for scrn dsplay opratons s not ncssary, thrby smplfyng nstallaton of th graphcal control panl.! Cauton Whn an rror occurs bcaus data s rad or wrttn outsd th PLC dvc rang, th rad/wrt opraton contnus rtryng untl th rror s rstord. For ths rason, th acton on th GP dsplay scrn may not sm to work.

Data Rad/Wrt btwn GP and PLC Dpndng on th PLC, th Systm Data Ara can b st to a crtan dvc. In that dvc, only th addrsss not usd by th PLC can b usd for th Systm Data Ara. Dvcs that ar hghlghtd wth a doubl lnd box n th dvc tabl dscrbd n Chaptr 2 and Chaptr 5 ar th only dvc aras that can b usd for th Systm Ara.

Turns ON f a BCD rror occurs whl D scrpt s bng usd. 7 For mor nformaton about D scrpt, rfr to th Tag Rfrnc Manual's scton 3.1 "D scrpt". 8 Turns ON f a zro dvson rror occurs whl D scrpt s bng usd. 9 Flng data. Turns ON f th data s not transfrrd to Backup SRAM. Flng data transfr s trggrd by th Control Word Addrss. Turns ON f th data can not b transfrrd from PLC to SRAM. 10 Also data transfr btwn PLCs s trggrd by th Flng Data Dsplay. Turns ON f th data s not transfrrd from PLC to SRAM only whn th transfr complt bt addrss s usd. 11 Flng data. Va transfr data to and from SRAM to LS ara, va Flng Data Dsplay. Whn usng D-scrpt, turns ON f a communcaton rror occurs whn th functon 12 mmcpy () s usd, or radng th data from dsgnatd Addrss Offst. Turns OFF whn data rad s normally compltd. Whn thr's no sttng of a connctd dvc for a gnrc SIO, f a sndng functon, 13 a rcvng functon, Control, Status, or th numbr of rcvd data s rad out, Turns ON. Whn radng out an xpanson scrpt xclusv functon (such as a charactr strng 14 opraton functon) va a gnrc SIO scrpt, or whn radng a gnrc SIO xclusv functon va an xpanson scrpt, Turns On. 15 Rsrvd 16

Bas Scrn Informaton (LS2033) Rsrvd (LS2034) 1 Scond Bnary Countr (LS2035) Tag Scan Tm (LS2036) SIO Cycl Tm (LS2037) Tag Scan Countr (LS2038) SIO Error Cod (LS2039) Th Rsrvd ara valu s ndtrmnat. Do not us ths ara. Bgns countng n 1 scond unts, aftr powrng up. Th data s n bnary format. Th tm t taks to scan th stup scrn dsplay tags. Th data s stord n bnary ms unts. Th data rnws at th pont whn th managmnt of all th objct tags s complt. Th ntal data valu s 0. Th masurd tm may dffr by ± 10ms wth th actual tm. Th tm t taks n 1 cycl, from th bgnnng to th nd, to scan th SIO objct (PLC ntrnal Systm Ara) and varous dvcs. Th data rnws at th pont whn th managmnt of th Systm Ara and all th objct dvcs s complt. Th ntal data valu s 0. Th unt s 10ms. Bgns countng n bnary unts, roughly whn th scan of th tags stup on th dsplay scrn s complt. Whn an SIO rror arss, th SIO rror cod dsplayd last s stord n bnary data. Maxmum Tokn Crculaton Spd (LS2040) (only whn usng n1 Mult-lnk conncton) Th maxmum tm t taks for th tokn packt (th rght to communcat xclusvly to th PLC) to crculat to th n numbr of connctd GP's.

Currnt Tokn Crculaton Spd (LS2041) (only whn usng n1 Mult-lnk conncton) Th currnt tm t taks for th tokn packt (th rght to communcat xclusvly to th PLC) to crculat to th n numbr of connctd GP's. Th data s stord n bnary ms unts. Th data rnws whn th currnt valu changs or a scrn chang occurs. Th ntal data valu s 0. Th unt s 10ms. If a problm occurs whch causs an SIO rror for an xtndd prod of tm, such as th unt's data transmsson cabl bcoms loos or dsconnctd, tc., t may ultmatly crat a Systm Error. Whn ths occurs, rst th GP. Whn usng th 1 Scond Bnary Countr and Tag Scan Countr valu as th W-tag's montor bt or D scrpt's trggr bt, and th SIO rror condton contnus, t may dvlop nto a Systm Error. Whn ths occurs, rst th GP. Spcal Rlays ar not wrt protctd. B carful not to us a tag to ovrwrt ths data. Whn usng a 11 conncton, th ntal Tokn Crculaton Spd valus rman (0). 18

20 1.2 Effcnt Data Communcaton Whn usng th PLC Drct Accss Typ, th GP unt communcats basd on th dvc addrsss st on ach scrn. As a rsult, th mor parts or tags st on a scrn, th mor data s transfrrd, rducng th communcaton spd. For ths rason, to spd up th rspons tms, mak data communcaton as ffcnt as possbl. On th GP, n addton to th ordnary communcaton mthod, thr ar th Block Transfr and LS Ara Communcaton mthods, whch upgrad data transfr ffcncy Block Transfr Whn dsplayng conscutv PLC dvcs on th GP, th GP automatcally groups th transmsson data nto a block, whch ncrass th communcaton spd. Th addrsss n th dtrmnd data numbr rang *1 must b conscutv to us Data Block Transfr. Whn parts or tags ar st up n conscutv addrsss, th GP automatcally rads th data as a sngl block. Whn you wsh to transfr a block, dsgn your part or tag layout so that th addrsss ar conscutv. *1 Th maxmum numbr of conscutv addrsss s lmtd by th PLC dvc. Rfr to th Appndx, "Maxmum Numbr of Conscutv Addrsss". 1

21 1.2.2 LS Ara Communcaton Us th LS ara for communcaton n th followng cass whn thr s dsplay data common to all scrns, whn thr s Trnd Graph block dsplay data, or whn a vdo wndow dsplay s usd. (GP-570VM only) To run LS Ara communcaton, frst st up th sz of th Radng Ara n GP's INITIALIZE sttng. Thn transfr th common dsplay data or block dsplay trnd graph data to th Radng Ara, allocatd n th PLC's ntrnal mmory. (Transfr accordng to th PLC laddr program.) By dong so, th data transfrrd nto th Radng Ara and th Systm Data s transmttd to th GP unt n on transmsson. By usng th LS Ara Communcaton mthod, no mattr what scrn s dsplayd on th GP, th Systm Data s transmttd contnually. Thrfor, to chang scrns quckr, us LS Ara Communcaton nstad of Block Transfr.! Important Us LS Ara transmsson only whn thr s data common to all scrns, whn Trnd Graph block dsplay data s avalabl, or whn a vdo wndow dsplay s bng usd. Othrws, communcaton ffcncy wll not b ralzd. Sttng up a Radng Ara that s too larg can caus th dsplay of tags that do not us th Radng Ara, or can slow data communcaton spd. Whn thr ar many parts or tags on a scrn, st all th parts or tags to conscutv addrsss. Block data transfr can b utlzd as a rsult, spdng up transmsson. 2
