Alicat devices come default with ASCII and Modbus RTU over RS-232. RS-232 interfaces are useful in systems with short-range, low-speed wired data connection. This is an inexpensive option when you only need to communicate with 26 to 32 devices in low-noise environments.<\/p>\n
How Alicat’s RS-232 communication works<\/a><\/strong><\/p>\n Modbus RTU has a simple setup and low memory requirement compared to most industrial protocols. It also has broad support among industrial control hardware and software systems. Modbus RTU has a standard set of universal commands, making it easy to use for those who are already familiar with the protocol.<\/p>\n [\/et_pb_text][et_pb_accordion _builder_version=”4.27.6″ _module_preset=”default” custom_margin=”1rem||1rem||true|false” hover_enabled=”0″ global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″][et_pb_accordion_item title=”ASCII or Modbus over RS-232 specifications” open=”on” _builder_version=”4.27.6″ _module_preset=”default” hover_enabled=”0″ global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]<\/p>\n *BASIS devices can have 247 Modbus devices on a network.<\/p>\n **CODA not compatible with Alicat’s ASCII.<\/p>\n Software and drivers<\/a><\/strong><\/p>\n [\/et_pb_accordion_item][\/et_pb_accordion][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” hover_enabled=”0″ global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]<\/p>\n Serial communication tutorial<\/a><\/strong><\/p>\n Choose ASCII and Modbus RTU over RS-485 if you are transmitting data across long distances or in a high noise environment.
