General Explanation: WinTr can connect more than one PLCs via distinct serial ports and MPI adapters. No limitation for connection number. Connected PLC's tag values reads and writes at the same time without certain order. Thus increase in the number of PLC's does not effects speed of reading data. Other advantage is that you don't need to connect PLCs to the same network in order to reach all PLCs with single scada.
Connect: You can activate only this network.
Disconnect: You can stop only this network. If all networks activated via Wintr connect button WinTr restarts this network automaticaly too.
StatusStrip: Information group at the ActiveX subsection. The first data in this group is Tag count. Then "Good" successful communication count. "Bad" is the failed communication count.
Receive Query: Bu bölümdeki Master’ın gönderdiği sorgular ile okuyup yazdığı register alanı gösterilir.
Rtu Network Menu: Modbus Rtu Station is the first element of this treeview menu. Second element is is the register table. When element selected tag list at the right filled with that element's tags.
Rtu Station: You can see PC port settings and Rtu .NET settings here.
Adress: You should enter this column the Tag's address in the PLC. You can enter HEX value here. All you need to do is adding "h" beginning of the value.
Tag Name: System gives the unused name to added tag. You can change it later then. All tag names must be unique.
Value Type: Shown number types: Boolean, Usigned int16, Signed int16, Bcd, Usigned int32, Signed int32, Floatpoint, Long Bcd, Time Of Day, Date. We think that some number types should be explained. Floatpoint type also known as single. Date type is the day number that named as word. Beginning of date is "1.1.1990".
Read Value: The values that read from PLC shown at this column.
To obtain the best performance issues must be considered: ActiveX tries to read all tags within the same group once. Calculates the query that will be sent according to the address data entered to the Tag list. If entered adress are consecutive reads all list at once.Number of bytes to be read at one time is limited to 250. Let's explain the subject with a couple example. Some query examples and total byte sizes are given below.
