Flexible Serial Port

Programmer Port

The T2EIT2N's RS-2320 programmer port supports the open T-series computer link protocol as well as the proprietary programmer protocol . This provides an easy connection to a higher level computer, an operator interface unit. a modem, etc-

Communication Port on the CPU Module

The RS-232C or RS-4 85 mufti-purpose communication port is standard on the T2N CPU . The interface is selected by a DIP switch,

The

RS-232C or RS-4-85 muIti-purpose communication port Is an

option on the T2E CPU . A M231 E or

M232E card must be mounted ire the T2E

CPU module .

 

By L,

ir.g these communication port, one of

the following three communication modes is available .

Computer link mode

T-series computer Iink protocol can be used in this mode . When the RS-485 is used, a maximum of 32 T2EfT2Ns can be connected to a master computer . By using this mode, all the T2E(T2N's data can be accessed by a master computer-

The T-series PLO programming software (T-PDS) can also be used in this configuration .
