PLC Connection GuideFor S7-200 PLC, Multi-HMIs-Multi-PLCs communication can be achieved using S7/200PPI driver, please refer to the settings below.IN EasyBuilder COM Port Settings, two important parameters must be set:1. [High station address (HSA)]:Setting Max. Station Number of HMI in PPI network.For the effectiveness of system operation, it is highly recommended that the HMI stationnumber starts from zero and go on sequentially. If there are 4 HMI in PPI network, setstation no. from 0 3, and [High station address (HSA)] to 3.Set HMI station number in [System Parameters] / [Model] / [HMI station no.]:2. [Gap update factor(GUF)]:The condition to pass a Token. In PPI network only HMI can hold a Token, PLC can onlybe controlled.When the HMI that holds Token communicates with PLC for a number of times that equalsto the value set here, HMI will pass the Token (control of PLC) to the next HMI. Forexample, if GUF is set to “1”, HMI will pass the control of PLC to the next HMI when reador write the value in an address.
PLC Connection GuideIf GUF is set to a bigger value, the HMI that holds Token will control the PLC for a longertime and therefore the Token won’t be passed to another HMI and cause failure incommunicating with PLC.A complete communication means HMI reads / writes PLC value for one time.Note: HMI sta. no. can not be the same as PLC sta. no.Highly recommended that HMI sta. no. starts from 0 and go on sequentially for theeffectiveness of operation.Available for EasyBuilder V4.50 and later.How to Import Tag:The tags created in the Symbol Table in Step7-MicroWIN software can be imported toEasyBuilder.1. In Symbol Table create the tags. Select all the tags and click the right mouse buttonthen copy the tags.2. Launch EasyBuilder, add the driver in the device list in System Parameter Settings,and then click Import Tag button.
PLC Connection Guide3. Paste the tags copied in step 1 and then click OK.4. Select all the tags and then click OK.5. If succeeded, the following message window shows.
PLC Connection GuidePass-Through Settings:[Designate client IP]: In Pass-through mode designate the client IP address to connectHMI. The “client” usually refers to Siemens Step 7 application.The following lists the system registers relevant to Siemens S7-200 PPI andSiemens S7-300 MPI Pass-through feature. [LW-10850: disable/enable (0 : disable, 1 : normal, 2 : IP limited) (siemenspass-through)] [LW-10851: destination COM port (siemens pass-through)]: Generally refers to theCOM port connected with PLC. [LW-10852: destination PLC station no. (siemens pass-through)][LW-10853: communication protocol (0 : invalid, 1 : PPI, 2 : MPI) (siemenspass-through)][LW-10854 to LW-10857: IP of connecting client (siemens pass-through)]: Displays current client IP address connected with HMI.[LW-10858 to LW-10861: IP of designated client (siemens pass-through)]: IfLW-10850 is set to 1, the system registers can be used to designate the client IPconnected with HMI.[LW-10862: connection status (0 : ready, 1 : client connecting) (siemens pass-through)][LW-10863: execution status (0 : normal, 1 : error) (siemens pass-through)][LW-10864: the last error (siemens pass-through)]
