9765-210 TRICONEX最古老的常用现场总线技术是Bitbus。Bitbus是由英特尔公司加强对的利用多总线工业系统中的系统通过分离缓慢输入输出功能来自更快的内存访问。

1983年，英特尔通过在现有的8044位总线微控制器上添加现场总线固件，创造了8044位总线微控制器8051微控制器位总线使用EIA-485在物理层有两个双绞线，一个用于数据，另一个用于时钟和信号。使用SDLC在数据链路层允许一个网段上有250个节点，总距离为13.2公里。Bitbus有一个主节点和多个从节点，从节点只响应主节点的请求。

Bitbus没有定义路由网路层。8044只允许相对较小的数据包(13字节)，但嵌入了一组高效的RAC(远程访问和控制)任务以及开发定制RAC任务的能力。在1990年电气电子工程师学会采用Bitbus作为微控制器系统串行控制总线(IEEE-1118)。

The oldest commonly used fieldbus technology for the TRICONEX is Bitbus. Bitbus is enhanced by Intel Corporation for faster memory access by separating slow input and output functions from systems in multi-bus industrial systems.

In 1983, Intel created the 8044-bit bus microcontroller by adding fieldbus firmware to an existing 8044-bit bus microcontroller. The 8051 microcontroller bit bus uses EIA-485 with two twisted pairs at the physical layer, one for data and the other for clock and signal. Using SDLC at the data link layer allows 250 nodes on a network segment with a total distance of 13.2 km. Bitbus has one master node and multiple slave nodes, and the slave node only responds to requests from the master node.

Bitbus does not define a routing network layer. The 8044 only allows relatively small packets (13 bytes), but it is embedded with an efficient set of RAC(Remote access and control) tasks and the ability to develop custom RAC tasks. In 1990 the Institute of Electrical and Electronics Engineers adopted Bitbus as a serial control bus for microcontroller systems (IEEE-1118).
