Technical Specifications
Core Processor & Memory Features
The
HIMA F8621A is equipped with its own microprocessor to handle specialized tasks independently. Specifically, it uses an HD 64180 microprocessor that operates at a clock frequency of 10 MHz, ensuring efficient and consistent performance for coprocessor functions. Additionally, the module includes 384 kbyte of static memory, which consists of CMOS-RAM and EPROM on two integrated circuits (ICs).
Furthermore, the CMOS-RAM in the
F8621A receives battery buffering from the power supply monitoring module F7131. This battery backup ensures that critical data in the RAM remains intact even during power interruptions. The module also features an operating system EPROM and RAM dedicated to a PLC master project, with the master project RAM buffered by the batteries on the monitoring module.
Communication Interfaces & Pin Allocation
The HIMA F8621A comes with two RS485 communication interfaces to support industrial data exchange. These interfaces are half-duplex and feature galvanic isolation, which enhances noise immunity in industrial environments. Each interface also has its own communication processor, ensuring smooth and reliable data transmission.
Moreover, the F8621A supports multiple transmission rates that users can set via software. These rates include 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, and 57600 bps. Users can also choose to take over the values set on the central unit (CU) via the DIP switch for added flexibility. The full pin allocation for the RS485 interfaces is as follows:
Pin 1: Not used
Pin 2: RP – 5 V decoupled by diodes
Pin 3: A/A – RxD/TxD-A (Receive/Transmit-Data-A)
Pin 4: CNTR-A – Control signal A
Pin 5: C/C – DGND (Data Ground)
Pin 6: VP – 5 V positive pole of power supply
Pin 7: Not used
Pin 8: B/B – RxD/TxD-B (Receive/Transmit-Data-B)
Pin 9: CNTR-B – Control signal B
Dual Port RAM for Fast Communication
The HIMA F8621A includes a Dual Port RAM (DPR) to facilitate fast memory access between the module and the second central module. This DPR enables high-speed communication via Bus 1, reducing data transfer latency and ensuring efficient coordination between the coprocessor and central modules. This feature is critical for applications that require real-time data exchange and quick response times.

Installation Guide
Pre-Installation Preparation
Before installing the HIMA F8621A, you need to check the H51q PES rack slot to ensure it matches the module’s 4 TE size. First, turn off the system power completely to avoid electrical damage during the installation process. Next, prepare the necessary tools, including a screwdriver and RS485 cables, to ensure a smooth installation.
Additionally, confirm that the power supply monitoring module F7131 is properly installed, as it provides battery buffering for the F8621A’s RAM. This step ensures that critical data remains protected during power interruptions after installation.
Step-by-Step Installation
Installing the HIMAF8621A is straightforward and aligns with H51q PES system rack installation procedures. First, align the module with the appropriate 4 TE slot in the rack and slide it in until it clicks into place securely. Next, secure the module to the rack using the provided screws to ensure stability and prevent loose connections during operation.
After physical installation, connect the RS485 cables to the corresponding ports on the module, following the pin allocation guidelines. Then, double-check all connections to make sure they are firm and free of loose wires. Finally, power on the system and configure the module’s communication parameters (such as baud rate) via software or DIP switch settings on the central unit.
Post-Installation Check
Once the F8621A is installed and configured, test its communication functions and memory backup to ensure normal operation. Check the RS485 communication between the module and other devices, as well as the Dual Port RAM communication with the central module. If any issues arise, recheck the wiring, power supply, and configuration settings to resolve them promptly.
