COM2接口的操作模式

串行接口COM2固定設(shè)置為無(wú)源模式（MMC接口）。

被動(dòng)模式用于執(zhí)行通信

借助DRUCK和EMAS塊進(jìn)行配置

用戶程序和連接到串行接口。

COM2的應(yīng)用程序特定初始化可以是使用SINIT功能塊執(zhí)行。

接口參數(shù)

被動(dòng)模式：默認(rèn)設(shè)置

同步：RTS/CTS

接口標(biāo)識(shí)符COM2:2

波特率：9600

 對(duì)于接收方向，文本結(jié)尾性格總是必要的

此默認(rèn)值文本結(jié)尾字符（CR）不得出現(xiàn)在消息文本也不在指定的用戶數(shù)據(jù)中EMAS塊。

對(duì)于COM2的被動(dòng)模式，接口參數(shù)可以使用SINIT功能塊進(jìn)行更改。如果更改的值不合理，COM2接口使用默認(rèn)值。

在被動(dòng)模式下設(shè)置SINIT塊或默認(rèn)值。3.3.12組網(wǎng)接口07 KT 93中央單元配備了一個(gè)特殊的并行接口。因此，它可以與使用附加通信的另一總線系統(tǒng)處理器模塊。附加通信

處理器有自己的外殼。兩個(gè)殼體（07 KT 93和通信處理器）

通過(guò)卡扣連接組裝。中央單元中使用的高速計(jì)數(shù)器07 KR 91、07 KT 92和07 KT 93獨(dú)立于用戶程序，因此能夠響應(yīng)快速響應(yīng)外部信號(hào)。其特點(diǎn)如下：計(jì)數(shù)頻率最大為10 kHz。計(jì)數(shù)器

計(jì)數(shù)端子05處的0–>1條邊（也指定為如E 62,00）。

計(jì)數(shù)器從–32768向上計(jì)數(shù)至+32767（8000H…7FFFH）。如果超過(guò)+32767，計(jì)數(shù)器跳到-32768。Operating modes of the COM2 interface The serial interface COM2 is fixedly set to the passive mode (MMC interface). The passive mode is used to perform a communication configured with the aid of the DRUCK and EMAS blocks between the user program and a device connected to the serial interface. The application-specific initialization of COM2 can be performed using the SINIT function block. Interface parameter Passive mode: Default setting Synchronization: RTS/CTS Interface identifier COM2: 2 Baud rate: 9600 Stop bits 1 Data bits: 8 Parity bits: none Echo: off Send Break Character: 0 Enabling End-of-text character for sending direction: no 1) Sending End-of-text character:1) Receiving End-of-text character:2)1) The default End-of-text character for the sending direction (CR) is not sent. Nevertheless, this default End-of-text character (CR) must not appear in the message text of the assigned DRUCK block. 2) For the direction of reception, an End-of-text character is always necessary. This default End-of-text character (CR) must not appear neither in the message text nor in the user data of the assigned EMAS block. For the passive mode of COM2, the interface parameters can be changed using the SINIT function block. If the changed values are not plausible, the COM2 interface uses the default values. In the passive mode the parameters established by the SINIT block or the default values are set. 3.3.12 Networking interface The 07 KT 93 central unit is equipped with a special parallel interface. It is thus possible to network it with another bus system using an additional communication processor module. The additional communication processor has its own housing. Both housings (of the 07 KT 93 and of the communication processor) are assembled by means of a snap-on connection.The high-speed counter used in the central units 07 KR 91, 07 KT 92 and 07 KT 93 works independently of the user program and is therefore able to response quickly to external signals. Its features are as follows:
The counting frequency is max. 10 kHz. The counter counts the 0–>1 edges at terminal 05 (also designated as E 62,00).
The counter counts upwards from –32768 to +32767 (8000H...7FFFH). If +32767 is exceeded, the counter skips to –32768.
