More than 90% of RKC products are supplied with a communication function, all of which have various types of protocols. In this section, we will introduce you to some protocols that are used in RKC products.

RKC Standard/ANSI Protocol

• All RKC products with a communication function offer this feature. As the name shows, it is based on ANSI X3.28 sub-category 2.5 A4 or B1.
• All functions, including initial setting, are covered to simplify instrument set-up.

Ladder Communication (Z-190)
This protocol is useful to reduce the programming on the PLC by the use of a HEX code and non-procedure protocol to communicate with a PLC. This type of communication is used in the SR Mini (H-PCP with Z-190 option).

Modbus (Z-1021)

Modbus is a communication protocol based on Modbus (RTU) by Modicon. By using an integrated protocol, PLC programming can be simplified and reduced while reducing total communication time in the communication between a PLC and many other devices in the field, such as sensors and actuators. The use of RS-485 hardware is cost-effective. This protocol is often used in linking FPD for FA and PA to control devices.
Memobus (Z-1001)

This is a communication protocol used in Yaskawa PLC. This protocol is used in RKC’s SR Mini systems.

Profibus
Profibus-DP protocol, specified by the Foundation of Profibus, is an open network that is designed to handle a large quantity of data at a high speed. RKC offers a COM-G communication converter that can be used with REX-F, CB, SA100/200, LE100 and the SR Mini HG System.

DeviceNet
DeviceNet, specified by ODVA, is an open network designed to handle a large quantity of data at a high speed. RKC offers COM-H communication converter that can be used with REX-F, CB, SA100/200, MA 900/901, LE100 and the SR Mini HG System.

SX bus
This communication is used to connect to SX bus used in a PLC from Fuji Electric. This field bus is designed to handle a large quantity of data at a high speed. RKC offers a special PCP for SX bus in SR Mini HG series, and TIO modules (excluding some modules) can be connected.

• Provides optional two-loop control with a single F9000.

ST-55/ST-56 Surface Temperature sensor

• Sensors for tiny surface temperature.
• The use of a thermocouple enables a tiny diameter at the top and measurement of an object with small heat capacity is possible.
• The use of adhesive tape on the measuring point fixes the measurement point firmly (Tefron covering, max. 260°C)
• Sensor length can be extended up to maximum of 800mm (Ceramic coat: D=0.32. Maximum length may differ depending on the element diameter).

H-PCP-J
The H-PCP-J is a new type of PCP (Power/CPU) module with enhanced functions that communicates to a PLC

Connectable PLCs

H-PCP-J can be used with the following types of PLC’s:

MITSUBISHI

• AJ71UC24
• A1SJ71UC24-R2/R4/PRF
• A1SJ71C24-R2/R4/PRF
• A1SCPUC24-R2
• A2CCPU24(PRF)

OMRON

New Features
Setting the output ratio is possible when used with a H-DO-G (output module), and it enables output ratio setting on each controller channel so that uniform temperature can be obtained in the plate temperature control application. It can also provide overshoot that arises from different thermal conductivity speed on the same plate.

Eight types of alarms can be provided from DO ports on the H-PCP-J, while a conventional PCP provides four types. As the PCP has two communication ports, it can be supervised from two hosts (PC and PC, PC and PLC). Further, in the conventional system, communication protocol had to be switched to RKC/ANSI protocol to perform initial setting, however, specifying one port as RKC/ANSI protocol enables easy initial setting. Below are newly added items for PLC communication:

• SV changing rate limiter.
• Control start/stop
• Switching multi-memory area
• Checking set value monitor
